Welcome to FBSwiki. This is the wiki for the text Feedback Systems by Karl J. Åström and Richard M. Murray. On this site you will find the complete text of the book as well as additional examples, exercises, and frequently asked questions.
Feedback Systems will be available in hardcopy from the publisher in April 2008. If you wish to use this for a course that is being taught before that time, please contact Richard Murray about local reprints.
 8 Jan 08: Version 2.9a is now online. This version has the nearfinal text and figures. There are still some small formatting issues that need to be worked out, but this version is very close to what will be sent to the publisher. One significant change from versions 2.8 and earlier is that we are now using the standard engineering convention for the direction of the Nyquist contour (agrees with MATLAB again).
 7 Jan 08: A supplement on optimizationbased control has been posted. This supplement contains additional material that builds on Chapters 6 and 7 (state and output feedback), including trajectory generation using differential flatness, optimal control theory and the maximum principle, linear quadratic regulators, receding horizon control, Kalman filtering and sensor fusion. The supplement is being used as a text for CDS 110b at Caltech for Winter 2008.
