9. Comments about teaching and course administration

- I think nobody will compain about Stefan. He did everything on this course on his own. Great patience, excellent teacher!»
- Great!!»
- The best lecturer and course so far!»
- Atleast one of Teaching/Tutorials/Lab Session - might have been handled by different person, just to learn a different way of thinking on a same problem. Except that the course is one of best I had.»
- »
- The commitment from Stefan was very appreciated and you really felt that he wanted you to learn.»
- Stefan did a wonderfull job in this course. Keep the good work up!»

Yes, it was, but most time was spent on learning Matlab»4 18%
No, it was tough but still OK»13 59%
No»1 4%

Genomsnitt: 2.5

- But I feel, if we have done something regarding machine model using S-Function(with Matlab) in Drives 1 course itself, it could have been reduced.» (Yes, it was too much to do)
- It was much to do, but the teacher clearly said that we would fall behind but after some weeks we would be in phase. So it didnt do anything» (Yes, it was too much to do)
- Might be better to have less preration tasks for the first lab, since the lab itself was pretty heavy.» (Yes, it was, but most time was spent on learning Matlab)
- Maybe, a more detailed presentation about how the S-function block works is needed. I spend many hours to understand this, and only when i searched the official matlab guide I understood what I had to do.» (No, it was tough but still OK)
- The work load was well coordinated with Power system operation that started of very slow.» (No, it was tough but still OK)
- Good to start at full power, usually no work in other courses» (No)

Yes, but I was in phase in the end»11 50%
Yes, then the work load would be more even»2 9%

- Also I would have learned less.» (Yes, but I was in phase in the end)
- Maybe i would have had time to really understand what i did instead of just doing it because i had to.» (Yes, but I was in phase in the end)
- It"s good to keep less work load when the exam is close, so don"t make lab 6 & 7 more time demanding.» (Yes, then the work load would be more even)
- I think the course has a lot things, and I think the projects are fine. I cannot see how else they can be arranged. Also reduced work in the end allowed us to be better prepaired for the exams.» (No)
- It is better to have a bit more to do in the beginning of the study period than havning it in the end closer to the exam» (No)

17. Should more of the projects be prepared as project 7, please comment.

22 svarande

Yes all, I did not learn anything of Simul/Matl implem.»0 0%
Yes, but only some of the last projects»7 31%
No»15 68%

Genomsnitt: 2.68

- The first assignment with the asymach function caused most problems. It would also be good if there were some graphs to look at to know if you have the right ones or not.» (Yes, but only some of the last projects)
- I think it is better for us to design everything in Matlab. Ok in the last two projects, designing the circuits in the matlab can be out of scope for this course, so I believe no changes are needed.» (No)
- I think I learn better when I do it myself.» (No)
- The last assignment wasn´,t as fun and instructive in that way that you got it all served. Still though it was nice to see that the last assignment wasn´,t as heavy as the previous ones. I believe some stuff should be added such that you need to explore some more than the commonly used blocks of Simulink.» (No)
- The setup is great as it is» (No)
- One is enough» (No)
- It is good to learn how to implement stuff i simulink. » (No)
- I learnd much of doing my own program in matlab and simulink!» (No)
- I believe it was a good way of doing it to let us type the code sometimes, which atleast increased my Matlab skills. But in a few cases the instructions could be a bit clearer, as it was a bit hard for someone who never really worked in the Matlab environment before. » (No)
- I think it was good as it was, the preparing was pretty fun.» (No)
- I feel it was good as it was. It didnt require a lot knowledge in Simulink to implement the model that we were using.» (No)

21. What should definitely be preserved to next year?

- Stefan Lundberg, Projects, Tutorials, Lectures»
- practical lab and all assignments»
- The Projects and the approvals of the projects.»
- Stefan Lundberg! and the study visit»
- The study visit»
- Stefan should definitely be preserved for the next year, outstanding teacher, knows what he is talking about, he is very structured and explains things in a good way. »
- The assignemts were good, even though the first ones took to much time.»
- The projects was excellent.»
- All the concept taught in the course is necessary to learn and but workload is difficult to reduce as the term is only 7 weeks.»
- Stefan Lundberg! Best lecturer ive had. I really felt like i could come and ask things without feeling stupid if there was something i didnt understand.»
- Stefan Lundberg, the man with a heart of gold. Have never experienced such a humble and helpful man ever before. He really made me feel that the important thing was actually to learn and not just to do for the sake of doing, and you can really feel that he is profesional and knows what he is talking about. All the time he spends on explaining in detail to ALL groups is incredible. I am extremely grateful for this and Chalmers should do their best to keep him around. »
- Project»

22. What should definitely be changed to next year?

- Stefan should have someone to help him during the computer lab occations.»
- Nothing»
- Nothing, but it would be fun to see a simulink control implemented on a real motor. Not just the direct-start/rated operation»
- hmm, its probably a good way of learning to do these projects, but I personally thinks that its to much to do, I need more time to sit alone and think about stuff to let it sink in. The fact that everyone was behind, made at least me just stress everything through to be able to catch up with the assignments. »
- The first assignment, more guidance is needed.»
- Help for Stefan to make approvals and help people with projects. The waiting time was sometimes very long.»
- More teachers to help with assignments»

23. Additional comments

- Maybe it was unplanned but the lack of tutors during some of the tutorials was not good. I believe it should have been stressful for Stefan but he didn´,t really show anything like that and still gave the students their time (and much extra), very good. To sum up: One of the best courses I´,ve taken regarding teaching and design and I really felt that I had learned a lot in the end of it. This mostly thanks to the teacher, Stefan.»
- I have to say that Stefan did a incredible good job. It seems like he put down a lot time and effort on this course and that has really paid off. Alot of creds!»
- One of the best courses I have taken in all of my studies. I give Stefan all of my respect and gratitude, one of the best teachers I have had.»
- Considering you have to get apporval on all assignments, maybe this course could be redone as a project course. We have to few project courses as it is.»
- Stefan should spend less time helping people implement stuff and more time on approvals because people can help each other.»
- I would like to thank Stefan for explaining all concepts clearly. Flexibility in time, given to present our projects is good.»
- Very fun course, maybe to much to do in the beginning, at least for me. Ive had some difficulties to really understand what we were doing in the start. So it took some weeks for me to really put a finger on what i did. Otherwise an interesting course. And stefan, never change!»
- Thanks for a good and interesting course!»
