- The second Hand-in took mooore time than 25 h...» (Around 20 hours/week)
- I only spend this much time the first 4 weeks. Then I had to drop the course because I was struggling to much with basics and the workload from my other course was even higher.» (Around 30 hours/week)
- I kid you not. Lectures + Exercises, but most of all assignments. They were crazy. Combine with the fact that my other course also was crazy on assignments. I didn"t manage to do any actual studying except for assignments until the saturday before the exam week. Not ok.» (At least 35 hours/week)

3. Is there a reasonable balance between different topics and activities during the course? Please give brief comments.

1) More time should be spent on (topic)...
2) Less time should be spent on (topic)...
3) Lectures - should there be more, less or as is?
4) Problem solving sessions –, should there be more, less or as is?
5) Assignments –, more, less or as is?
6) Other?

(på denna fråga var det möjligt att välja flera svarsalternativ)

- The problem sessions are good but should be more of solving numerical probems then proving evidence type. The assignments where good but the third one could have been a little more exciting. The amount of lectures was good and Bo was a very good teacher.»
- I think that everything was good. But the problem solving sessions should be maybe twice a week instead of once. Maybe its better to gain more practice.»
- Good balance!»
- For the cases 1-3 the spent time was reasonable, no change is necessary. it"s better to have more problem solving sessions, like having two sessions every other week. 3-Assignments are nice and well designed, but please increase the deadline for assignment two next time(or any assignment which is difficult)»
- 1)Observers 2) 3)2-3 more lectures 4)More of problem solving and maybe scheduled time for self studying problem solving»
- I think there have been a good balance between different topics and between different activities.»
- Assignemnts could possibly have been a little bit smaller and some more assignment consultation would definitely be welcome. Some of the exercise lectures could have been used for supervised assignment work in a computer studio instead.»
- 1) More on practical implementation maybe. 2) Less on proving stuff (problem solving sessions). 3) As is. 4) Less. 5) As is.»
- Less time should be spent on derivation of convex optimization. More time should be spent on explaining stability. Problem solving sessions should there be more. Assignments as it is, but maybe more hints, because it was sometimes frustrating.»
- More problem solving sessions would be nice. Also more consultation hours.»
- it was good»
- Less assignments or alternatively assignments instead of an exam since the course is not so much calculating by hand.»
- Very good balance»
- 4) Problem solving: More "useful" exercises. Instead of profs. 5) Assignments: Great content, but a little to big...»

Goals and goal fulfilment

The course syllabus states the course goals in terms of learning outcomes, i.e., knowledge, skills and attitudes to be acquired by the student during the course.

4. How understandable are the course goals?

20 svarande

I have not seen/read the goals»4 20%
The goals are difficult to understand»3 15%
The goals give some guidance, but could be clearer»3 15%
The goals clearly describe what I am supposed to learn»10 50%

Genomsnitt: 2.95

- They are quite good. Might be better to shorten them into one sentence each.» (The goals clearly describe what I am supposed to learn)

5. Are the goals reasonable considering your background and the number of credits?

Answer this this question and the succeeding one, only if you do know the course goals.

18 svarande

No, the goals are set too low»0 0%
Yes, the goals seem reasonable»17 94%
No, the goals are set too high»1 5%

Genomsnitt: 2.05

- However, if prerequisites also was one otimization course, you probably could go more in depth on the control part.» (Yes, the goals seem reasonable)

6. Examination is a challenge for this course. Which solution do you prefer?

19 svarande

As this year»6 31%
Graded assignments and written final exam»9 47%
Graded assignments only»2 10%
Assignments followed by individual oral exam»1 5%
Other, specify …,..»1 5%

Genomsnitt: 2.05

- Maybe shorten assignment 2.» (As this year)
- a small final exa maybe, but a possibillity is definately to have mor extencive hand ins with 3-4-5 grading. » (Graded assignments and written final exam)
- It"s nice to earn some points for the time we spend on the assignments and the preparation for their oral exam. Or you can consider bonus points in advance for every passed assignment. Since the exam is difficult, having some points helps to reduce the stress.» (Graded assignments and written final exam)
- I think the oral exam after the assignments is not necassary. The grading should be based on the report. A solution after the assignment how it should have been done, would be great.» (Graded assignments and written final exam)
- and maybe oral exam after each assignment.» (Graded assignments only)
- Graded assignments only or assignments followed by individual oral exam. Doesn"t matter too much between these two. The reason is that it was crazy much to do this year. Not because it was many assignments but because they took time. Also the exam is written by hand while the actual things you use in the course are for computers» (Other, specify …,..)

7. Did the examination assess whether you have reached the goals?

19 svarande

No, not at all»0 0%
To some extent»10 52%
Yes, definitely»8 42%
I don"t know/have not been examined yet»1 5%

Genomsnitt: 2.52

- I think it was a bit difficult, maybe we needed to solve even more exercises, I don"t know.» (To some extent)
- however, it is maybe not so good that the exam which gives 3 HEC will give teh grades for the entire course.» (Yes, definitely)

- I think Bo is a good teacher, but sometimes found it hard to follow his train of thought. He spoke often in long sentences and with difficult words, which made it easy to lose his point.» (Some extent)
- Faisal is always available even when he is busy. It"s a great Phd.» (Great extent)
- The teacher was very successful in presenting difficult topics in a very comprehensible fashion, and his teaching style, i.e. teaching speed, use of visual aids, lecture notes was really outstanding. » (Great extent)

- Instead of buying a text book, the course notes could be extended to cover the topics that are taken from the book. » (Small extent)
- I didn"t use the book so much. But the lecture notes were great. So i had bad invesments on the book, but maybe its good to have the book for the future.» (Some extent)
- Much due to many hand ins in other courses i only had the time to read the book in the beginning of the course. The lecture notes are really good though.» (Some extent)
- The book was really good in the first chapter, even better than the lecture notes, but I gradually disconnected from the book and stayed with the lecture notes although the mini tutorials were still helpful. I think it"s nice if the lecture notes contain a couple of more examples.» (Some extent)
- Some times a bit more detailed explanations would have helped. The complementary litterature for the course could have been more extensive. I got stuck at assignment 2 and I couldn"t find any references that could explain set point tracking to me in a satisfactory way. That"s why I eventually had to drop out of the course. Multiple examples demonstrating key subjects through out the course would have helped alot.» (Some extent)
- The compendium was really good the book was very hard to understand until the end of the course. This might be because before the last week i didnt have enough MPC knowldegde to understand the book.» (Large extent)
- The course book have not been that helpful due to different notation and lack of detailed explination of different topics.» (Large extent)
- Not the book though, have barely read it. But the lecture notes were good.» (Large extent)
- The lecture notes are great!» (Large extent)

10. What combination of text for the course do you prefer?

A compendium, tailor made for the course.»8 40%
No opinion»0

Genomsnitt: 3.2

- As I mentioned, lecture notes could have contained more examples, and more explanations. It"s also good to use the same notations as the book to avoid confusion. this was especially giving us problems in some exercise session, but just like you, I don"t like book"s notations.» (More comprehensive lecture notes and a book for reference.)
- The book we had was good, but a bit old.» (More comprehensive lecture notes and a book for reference.)
- The book doesn"t need to be mandatory. This makes it legal to make copies (<15 pages) of the book for the teacher!» (More comprehensive lecture notes and a book for reference.)
- Built from the lecture notes, but with some reference material (appendix maybe)» (A compendium, tailor made for the course.)
- It would be good to avoid to different sources with different notation.» (A compendium, tailor made for the course.)

- Faisal was alone as a TA, so I don"t blame him, but he did not have much time at all. He didn"t reply to mails either.» (Rather poor)
- The consultation times have been a good opportunity for asking questions.» (Rather good)
- Great professor and very helpful TA.» (Very good)
- The TA, Faisal, is really knowledgeable, and explains the issues nicely. He was one of the anchors of this course. » (Very good)
- The consulting opportunities were very good. Nevertheless the assistant had a lot of work. Maybe it would be better to have two assistants or a assistant and a student who have done this course already (for the next year)» (Very good)

I did not seek cooperation»0 0%

Genomsnitt: 3.25

- I didn"t now anyone from before, I"m bad at making contact and I missed out on the first week of the course because of illnes. So i did not have much cooperation with fellow students, I think this was a major reason for not doing so well in the course, but what little cooperation there was it worked good.» (Rather well)
- The group work was good, but it would have been nice to work more togehter within the class.» (Rather well)

Genomsnitt: 3.9 (bidrar till totalt genomsnitt/jämförelseindex)

- It did teach me some nice things. But I would have a hard time recommending it unless I knew for sure that it would change in workload.» (Adequate)
- dedicated teachers» (Good)
- Good lectures and assignments on a very interesting subject. The course literature was not perfect though and more help with assignments would have made the course even better.» (Good)
- Really interesting and "different" topic in control theory.» (Excellent)

17. What should definitely be preserved to next year?

- The assignments with the 15min talk with the PA afterwards. especially the 15min increased the understaning a lot.»
- hand ins, a good way to learn the practice.»
- 1-Bo: he is just perfect at explaining the concepts. 2-Faisal: as mentioned before, he knows the subject very well, and he has a nice helpful personality. 3-Lecture notes and assignments. 4-Company visit, maybe this time application of MPC in vehicle safety, at VOLVO cars.»
- The assignments, but perhaps »
- the assignments»
- The consulting hours and the problem solving lessons.»
- Course notes.»
- the idea of using assignments as parts of examination...»
- Bo, Faisal, the lecture notes and the assignments»

18. What should definitely be changed to next year?

- The problem session that was about Kalman filter and estimators should have been with numerical problems rather than the proof of some theorems..»
- it would actually be nice to have some clear comparising examples together with the hand ins, maybe provide the sam problem together with basic PID regulator and compare the performance. Maybe also introduce a lab?»
- Less proof and more applied tasks and calculations on problem solving sessions and final exam.»
- Maybe more assignments, but less work per assignment, so that the workload remains the same, but the problems are more structured / easier to solve. »
- get rid of viva voce»
- ... but they should be more comprehensive. And there should definitely be more scheduled time to ask questions. Faisal was far too stressed to help even at scheduled time.»
- Assignments. Exam form. More TAs. (poor Faisal)»
- Solutions to the exercises should preferably be available right from the start of the course. I am well aware of the workload on Faisal and greatly appreciate his efforts to give solutions to the exercises.»

19. Additional comments

- Both Bo and Faisal did a good job even though it sometimes was clear that it was the first year the course was held.»
- Comments of the lecture notes: I think it would be a good idea to explain more detailed why there is, or why there isn"t a lack of feedback in the different cases of the topic described in chapter 5, page 38. Also, if it"s possible it would perhaps be a good idea to clearify the issues of least square state estimation (Ch. 6) and stability (Ch. 10) with some pictures. »
- Faisal have done a gread job. The lectures have been nice, too.»
- The course takes a lot of time. »
- Very good course given in an inspiring way, made me very interested in this subject. I would definitely take a second couse on MPC.»

20. What is your assessment (brief comments) of:

1) Lectures
2) Problem solving sessions
3) Consulting sessions
4) Assignment 1
5) Assignment 2
6) Assignment 3
7) Interviews on the assignments ("viva voce")
8) The company visit

(på denna fråga var det möjligt att välja flera svarsalternativ)

- 1)good 2)mostly good 3)very good, but would have been good if both BO and Faisal could attained every time since there where a lot of waiting time,. 4,5)good 6)coudl have been a little more exciting 7)Very good and useful. increased the understanding a lot. 8)wasn"t able to attend, i wish i could because from what i heard it was very appreciated and i think its a good idea to show the students a real life application of the theories from the course.»
- 1)lecture were great. 2) Problem solving sessions: it was ok, too much material and less time. 3) Consulting sessions: good 4) Assignment 1: good 5) Assignment 2: good 6) Assignment 3: good 7) Interviews on the assignments ("viva voce"): good 8) The company visit: it was intressting and we had a good time and good explanations of MPC.»
- All good!»
- 1- Just perfect 2- Very Helpful, but not enough 3-Essential 4- Assignment 3 was too easy, assignment 2 was too difficult, assignment 1 was just right! 5-Interviews were helpful to understand some issues, and thanks to Failsal"s friendly attitude not stressful. 6- Company visit was eye-opening»
- Great lectures and if proofs still have to be a part of this course, add them to the lecture material and skip them at pss. PSS. Too much proof and not enough applied calculations. Assignment 1 was good, the second could have more problem description AND IF you can get bonus points on assignment the report requriements HAVE to be more clearly statet, they were NOT well statet.»
- Very good lectures. Kind of hard problems to solve during the problem sessions. Consulting was great. Assignments was good. The interviews is a very nice way to really understand the assignments. The company visit was really nice. Especially since we not see the theory in practice so often at Chalmers.»
- 1) Generally very good, but in some part there were to much of blackboard formula derivation 2) Some nice, but some of them quite hasty. The exercises could have been more like the ones 3) Didn"t attend 4) Nice, and at a good level 5) A little bit unclear formulations, otherwise quite nice. 6) Could have been more extensive and include some more coding, not just tuning 7) Too short, but a good idea 8) Didn"t attend»
- 1) Lectures have been good. 2) Some problem solving sessions have been quite strange, Some tutorials have been very theoretically and have seemed quite irrelevant for the course: for instance tutorial 3. Moreover if one intend to include thinks like Bellman"s equation and Matrix calculus I think it would be a good idea to explain this math before just throwing it into some tutorials. (These things were not stated as prerequisites.) 3) Consulting sessions have worked well. 4) Assignment 1 worked well. 5) If not just right answers but also a more well written report than usual is a demand for achieving bonus points then this should be stated clearly in advance. (Not just put on the web page.) 6) This assignment worked well. 7) The interviews is a very good element in the course! 8) Didn"t attend. »
- 1) Really good. 2) Only attended a few, but better to have less theoretical proves and more practical oriented. 3) It"s better to help one group for max 5 minutes and then move to the next, than to discuss with the same group for a very long time. 4) Gave a good introduction to MPC. 5) Was good but a bit too time consuming. 6) Was good. 7) They were good. 8) It was fantastic! You should really keep that.»
- 1) good 2) good (should be more time) 3) very good 4) excellent 5) good, but a clearer structure and more explanations concerning the solutions at the end would have been nice 6)ok, but I think it was not necassary. Maybe a other topic would be more interesting 7) good, because they provided more insight, but the grading should not be based on that 8) -»
- 7. viva voce is almost pointless to me. It doesn"t really asses if we took part in the assignment.»
- 1, good, but could be more comprehensive. they were theory heavy, making it hard to absorb the material. 2, Faisal was a bit stressed, which made it hard to ask questions/get good answers. Also, the solving of exercises could have been done in a more pedagogic way, for example by explaining the thoughts leading up to the solution. Not just presenting it. Otherwise it was good, Faisal was very ambitious and enthusiastic. 3, the TA was stressed and did not take his time to answer questions on the consulting session I went to. On that occation he came one hour late and stayed for five minutes. Not good! 4-6, good way of learning and examining. It could be more clear what the criterias were for bonus points, and how the solutions should be presented. 7, as long as there is time for this I think it is good, but it should not steal time from e.g. consulting sessions. 8, good thing, though I could not participate.»
- 1. Ok 2. Ok-ish. Faisal takes more than he can chew. 3. Poor. Too many questions, too little time. Too few TAs 4. Too hard unless you remove the exam. 5. Too hard unless you remove the exam. 6. A bit easier, but still took a fair amount of time. Alot better than the former two, but could use a guide on what the different variables mean. It took some time to figure it out at first. 7. Was good. Learnt more from them than from the assignments.»
- 1) I"m very satisfied with Bo"s lectures, easily amongst the best lectures I"ve attended at Chalmers so far. 2) Very good. Well chosen exercises. 3) Helpful without giving away too much information, made you think on your own. 4) Good, not too difficult. 5) Very good! A great deal of my understanding of MPC was gained from completing this assignment. 6) Ok, nice to get a "feeling" for how different tuning parameters effect the system. 7) Good, some challenging questions, could have been a little longer. 8) Very nice to see MPC in practice! Well planned, good presentations.»
- 3) More than one person to consult? 5) Good, but big! 6) Great that you reduced it when you saw the workload on the two other. 7) Good! 8) Great with the company visit, and the close connection with Ass.2!»
