- Could not attend all lectures because of a scheduling conflict with the course Model Based Signal Processing» (25%)
- some of the lecures was interfering my other course. » (75%)
- The course schedule was not well planned. The lectures conflicted with my (and 6 more students) other course named "model based signal processing". The interesting point is that this course and model based signal processing are both recommended for students of control track. Although the administration knew (we contacted them) about this conflict some weeks before the start of study period, they took no effective action to resolve it. As a result, we missed 30% of the lectures of adaptive and nonlinear course and some lectures in the other course. Despite our request, they did not even changed the time of problem solving session of this course which also conflicted with model based signal processing lecture times. Therefore, we lost all the problem solving sessions and could gain nothing from this sessions. It may not be fair to say that they didn"t really care about our problem... but it seems to me like this » (75%)
- 100% of attending was not possible due to course collisions» (75%)
- Schedual didn"t work out with this course and SSY215, atenden 65% give or take» (75%)

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.

3. How understandable are the course goals?

19 svarande

I have not seen/read the goals»5 26%
The goals are difficult to understand»0 0%
The goals give some guidance, but could be clearer»7 36%
The goals clearly describe what I am supposed to learn»7 36%

Genomsnitt: 2.84

- The course must be divided into two parts. Each for one study period» (The goals give some guidance, but could be clearer)
- the course goals should be revised (preferred) or the course should be renamed to "Introduction to nonlinear and adaptive control" (themes are mostly covered in a "to give an overview"-manner)» (The goals give some guidance, but could be clearer)

4. 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.

15 svarande

No, the goals are set too low»1 6%
Yes, the goals seem reasonable»14 93%
No, the goals are set too high»0 0%

Genomsnitt: 1.93

- due to the variety of themes covered in the course a convenient depth is not taught and probably not possible to cover in that short time» (No, the goals are set too low)
- The goals are reasonable but that much amount of material is too much to be covered in 8 weeks. As a result some topics were oversimplified without discussing them in detail.» (Yes, the goals seem reasonable)

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

- The material were very poor considering the topics which were due to be covered. However, the appendix provided by the teacher helped a lot.» (Small extent)
- course book is lacking a lot information in a number of derivations. the exercise booklet contains a lot of mistakes and misses a number of solutions. furthermore, some exercises require knowledge which haven"t been taught and which is not covered in the course book.» (Some extent)

- powerpoint presentations were not available in advance and have not been updated to the end of the course. the course collided with a number of other courses, even though they are in the same master program. very sad was, that the willing to help in this case (for example shift the exercise session to the consulting hour) seemed to be very little.» (Rather badly)
- The computer lab could have been published earlier.» (Rather well)
- I recommend that the lecture slides should be updated after each lecture, not at the end,» (Rather well)
- The handouts did not really help to realize the goals mentioned in the introduction session» (Rather well)

- Micheal, the TA, was a very good, knowledgeable and smart TA and always explained the stuff patiently. However, the opportunities to ask questions for me wan not good at all for the reasons I have already mentioned.» (Rather poor)
- Good with consulting hours.» (Rather good)
- For the lab and second assignment there could have been a bit more help/hints/examples during the problem solving sessions or an extra session in a class room with computers insted of consulting in Lunnerummet.» (Very good)

- more based on the faced that I follow to mutch courses» (Too high)
- Hand out the handins earlier. Since we had alot of things concentrated to just 2 weeks this period in both this and another course the work load was way to high those 2 weeks. All the other week has been pretty normal in workload.» (Too high)

- The course should be split up in three courses and cover all the topics separately to be able to provide more profound knowledge. The sentence "i skip the details" was said far too often. I think the professor and teaching assistant have both good teaching skills, its the course content and literature which have to be revised. More control-related courses would be good for the master program anyway» (Fair)
- In my opinion, professor Edgart is the best one and indeed very qualified for this course. And he is really knowledgeable and expert in this field. But this course must be divided into two parts to gain the best out of the course.» (Good)
- An fun and interesting course. Probably the best course so far!!» (Excellent)
- Sometimes the lectures got a bit too theoretical and it got hard to follow what was really done and why (mostly the last part which also was presented to be difficult). Difficult in a way that also made it hard to come up with any relevant questions. It is hard to come up with any ideas of how to improve or simplify, but maybe some simple “,real”, example would help and make it more intuitive. Simple examples are always good.» (Excellent)

14. Was the study trip to Preemraff a valuable part of the course?

19 svarande

No, not at all»0 0%

Genomsnitt: 3.42

- Very nice trip. Important to see how the theory is used in the real world.» (Yes, definitely)
- I think people who did not attend really missed an opportunity.» (Yes, definitely)
- Should give more time to the lectures on Control theory and not spend so much time on general plant presentation lectures. Guess that was the plan this year but since we where behind schedule it didn"t really work.» (Yes, definitely)
- Maybe couple it even stronger to the last assignment. Skip the first presentation (about the economy) and instead spend more time with the last presentation/lecture about the control of the fractionator.» (Yes, definitely)

15. What should definitely be preserved to next year?

- Everything!»
- Everything except the Optimal Control Chapter. I felt it was very rushed and it deserves its own course to get a good understanding»
- The examinator, lectures and the exercise sessions»
- Company visit»
- The passitivity part and Lyapunov"s stability concepts.»
- The problem-solving sessions with both examples on the blackboard and consultation.»
- All the assignments have been of help along with the computer lab, so the should definitely be preserved to next year.»
- The teacher»
- Preemraff. The very good lectures with black bord/projector combination and the matlab/simulink examples. The problem solving sessions.»
- mikael thor as teaching assistant, he is very helpful»
- Professor and teaching assistant»

16. What should definitely be changed to next year?

- More consulting hours during hand in 2 (MPC)»
- I think the Optimal Control Chapter should be removed and probably give more time to Adaptive Control. »
- nope»
- More time should be spent on nonlinear control techniques which were just overview so quickly because of lack of time. Moreover, the adaptive and optimal part must be offered as a separate course.»
- Would be fun to have a lab with som practical elements, for example controlling a real cart-pendelum setup. The computer lab felt a bit strange as you almost did the whole lab at home as preperation.»
- An assignment or a lab session on a simple adaptive control problem would really help since the subject is a little bit difficult to grasp without practice.»
- Fix the pendulum! It felt really disappointing not to be able to try the real thing. Maybe some more "real" simple labs or one larger "real" project where most of the things we learn can be implemented. The lack of hands-on in this course makes it feel too theoretical and leaves a big gap in the understanding of how to implement all things in real applications.»
- The course content, it should be taught in more depth.»

17. Additional comments

- Would have been nice to try the pendulum controller, developed during the lab, on a real process.»
- Good Course»
- Thanks professor Edgart and Micheal for all they have done to provide a high quality class. Thanks again to Bo for arranging the company visit.»
- Other than the above, everything went well.»
- Bo Egart has the unique combination of both beeing an expert in an area and in the same time a very pedagogical and exellent lecturer, which most often seems to be a contradiction. Mikael Thor was an exellent course and exercise tutor, one of the best I have had on Chalmers, very good at explaining, very humble to the difficulties in this subject which made it easy to ask questions about anything without feeling stupid. Also well prepared and obvious that he knows the subject very well.»
