Ph.D. Course: Multivariable feedback control using frequency-domain methods.

(Multivariabel frekvensanalyse)

Norwegian University of Science Technology.
Course number: 43917 (DIE3917)

Instructor: Sigurd Skogestad

Taught last time: Spring of 1999

The course has been given every year since 1989 (except in 1995 and 1998), but it is now discontinued - it is replaced by a new 4th year (advanced undergraduate) course SIE3085 by Professor Morten Hovd given the first time in the spring term 2001.

Level: Introductory graduate (Ph.D.)

Grading: The project counts 20% and the final exam 80%

Textbook: S. Skogestad and I. Postlethwaite, Multivariable feedback control - analysis and design , Wiley, 1996.

This is a fairly extensive course. It requires that the students have some background in multivariable control and in state-space system theory (some students do not have this background, but they must then expect to spend up to 20 hours per week on the course).
