Corrected homeworks (HW2) can now be picked up in the Reglerteknik II out-box, ITC, house 2, floor 2.


Due to a misstake, you could sign up for the process labs on occations when the lab-room 2314 was not booked (compare with your schedule). Because of this EVERYONE will have to SIGN UP AGAIN. This time the lists should be correct. The new lists will be on the door of 2314 as of tomorrow friday 1/10. Sorry for this.


Corrected homeworks (HW1) can now be picked up in the Reglerteknik II out-box, ITC, house 2, floor 2.


Please note that there has been some last minutes changes in the schedule.

F8 is moved from Sept 20 10-12, to Sept 20 8-10, room P2247.

BL2b is moved from Sept 29 13-15 to Sept 28 15-17.

2. Teachers and supervisors

The Division of Systems and Control is located at Polacksbacken, house 2.

Name Function Room Phone Email

In addition, Bengt Carlsson, Hans Norlander, and Soma Tayamon will give a few of the lectures and problem solving sessions.

Note that for all administrative and practical aspects you should as a first choice contact the undergraduate office (IT-kansliet, room 4213).

3. Prerequisities and background

It is assumed that the participants have working knowledge in the following areas:

  • Continuous-time control systems.
  • The program package Matlab. The computer laboratories and most of the homework assignments assume that you are familiar with Matlab. In the homework assignments you will be expected to do your own programming. You will also use Matlab's Control Systems Toolbox frequently.
  • Some basics of random processes or signal processing is an advantage, but not fully necessary.

Links to some general background material to download is available below.

4. Literature and course material

The course is based on the textbook

  • Torkel Glad and Lennart Ljung: Reglerteori - Flervariabla och olinjära metoder. Studentlitteratur, andra upplagan, 2003 (RT). [There are no larger differences from the first edition of 1997.] It is also available in English as Torkel Glad and Lennart Ljung: Control Theory - Multivariable and Nonlinear Methods, Taylor and Francis, 2000.

Course material for sale at UTH-gård:

  • Exercises Control Theory (2010 edition; includes solutions). (120 SEK).
  • T. Söderström: Random Disturbances - Models and Analysis. (30 SEK)

Further course material include

  • Computer laboratories
  • Laboratories ['LQ control of the seesaw/pendulum process'; 'Model predictive control of the tank process']
  • Homework assignments

We have a limited edition of this material. It will be handed out during the first lectures in the course. You can also get access to this material through the web, see below.

5. Computer facilities

For completing the homework assignments you will need access to Matlab and its Control Systems Toolbox.

The software is available in our PC lab (room 2315). To have access to the computers in the PC lab, a student account at UpUnet-S is required. You will need your UpUnet-S user name and the C password in order to login. Information about how to get a UpUnet-S account can be found here. When solving the homework assignments you may need to use Matlab and the Control Systems Toolbox. For more information see the document 'Matlabs Control Systems Toolbox och LTI-object' which is handed out at UTH-gård, or can be found under 'Background material' below. You can of course use the software in the PClab. Another alternative is to run the software over the web. In that case you will need to use your UpUnet-S identity. How to get media and access to the license is described here.

6. Some hints

The course contains a lot of useful stuff, that is also practically important. You may think that there is a lot of theory to penetrate. Here are some friendly advice for how to facilitate the learning.

  • If you read the chapters in advance before each lecture (even if you skim through them), you will find it easier to both follow the presentation, and to improve your understanding during the lectures.
  • The Computer laboratories as well as the Laboratories are aimed to be good vehicles for deepening your knowledge and understanding. We assume that you have prepared yourself accordingly, so that you can take full use of these parts of the course. Take the oppurtunity to attend the computer laboratories and ask for help with issues you find difficult in the labs. A considerable part of the computer laboratories are aimed as preparations for the Laboratories.

7. Examination

The structure of the exam is the following:

  • One final exam, max 50 units.
  • The laboratories, pass or fail (no gradings).
  • Homework assignments ('inlämningsuppgifter'), max 3 units each.

The units gained from the homework assignments will give credit in the final exam. The final exam will contain one problem (6 units out of the total 50) that can be used as an alternative option. For each homework assignment there will be a strict deadline when you can hand in its solution.

Preliminary grades: 3 = 23-32, 4 = 33-42, 5 = 43-50.

During the exam, the course literature, mathematical handbooks and tables, and calculators are allowed. No set of exercises and solutions is allowed.

Some further policy for the examination:

  • New versions of the final exam are given in January 2011 and August 2011. If only few persons registrate at these occasions, we may arrange an oral examination instead.
  • The results of the homework assignments that are handed in during fall 2010 are valid until August 2011. Passed Laboratories are valid without any time limit.

8. Structure

The course consists of

  • 11 lectures ('föreläsningar')
  • 7 problem solving sessions ('räkneövningar')
  • 3 computer laboratories, 2 hours each ('beräkningslaborationer')
  • 2 laboratories, half a day each ('laborationer') (compulsory)

The computer laboratories will take place in room 2315. The laboratories take place in room 2314. Please note that you need to use your student account at UpUnet-S (user name and C password are required) in order to run the computer labs.

The detailed schedule for the laboratories will be arranged later. You will have to sign up for the two half-day laboratories. The signing lists will be posted on the door of the control lab (room 2314) on September 28, 15.00.

The computer laboratories and the regular laboratories are essential parts of the course. They contain many tasks to carry out. In order to pass them, it is necessary that you prepare yourself carefully in advance according to the instructions for the individual laboratories.

Homework assignments (and when needed also Laboratories) are to be handed in at the marked mailbox (no 26) in the row of mailboxes, (second floor, house 2). We will also hand out your corrected homework assignments and laboratories there. Returned solutions that are not collected by November 19, 2010 will be thrown away.
