Exercises

LP3 Fridays 10.15-12.00 in E:1147:

The recommended reading below should be seen as a guide. Generally you will have to read a bit more outside of the recommended reading in order to grasp the concepts, but it will be a good place to start. Johansson refers to the "Lecture notes: Predictive and Adaptive Control" (2020 edition) and Åström refers to the book "Adaptive Control" by Karl-Johan Åström (2009 edition).

Exercise Materials

    1. Exercise 1 with exercise_1_public.zip. Notice that this computer exercise is held in Lab B, please sign up in advance.
    2. Exercise 2 and solutions
    3. Exercise 3 and solutions
    4. Exercise 4 and solutions
    5. Exercise 5 and solutions
    6. Exercise 6 and solutions
    7. Exercise 7: Old Exams (see below) and Questions

Laboratory Sessions

Sign up for the laboratory sessions here, and do so at least one day in advance. Note that Lab 1 is now updated, and there is no preparations needed apart from reading the relevant chapters in the course book.

Home Work Assignents

Please send your solutions by the deadlines to the emails by the specified deadline. Solutions should be submitted in individual short reports written in a PDF format. Reasonable cooperation is allowed (but not copying other persons solutions).

Please send your solutions by the deadlines to the emails mentioned in the handins. You will get feedback on your solution, and if it needs revision, you will have to submit a revised solution within a week of receiving the feedback. 

Exam

Tuesday, March 17, at 14-19 in MA:10A-B. Some old exams are given below.

Projects

The projects will be done individually or in small groups of 2-4 students. A list of project proposal can be found in the project list. You should sign up for a project no later than Sunday, March 1. The deadline for the project report is April 29 unless otherwise agreed with the project supervisors. The project should be presented Wednesday, April 29, at 10:15-12:00 in the seminar room M:2112B of Dept. Automatic Control. All project groups should give an oral presentation of 5-10 minutes. Presence mandatory for students of FRTN15. WELCOME!
