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 near-final 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 optimization-based 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.
- 14 Dec 07: Version 2.8 will be posted in the next few weeks and will contain all of the final text plus most of the final figures for the book. The book is on schedule to be available to instructors April 2008 and available for general purchase by May 2008. Instructors wishing to use the text for courses in the winter or spring of 2008 should contact Richard Murray about the possibility of getting a preprint version.
- 14 Sep 07: Version 2.7c is now online. This version is being used in CDS 101/110a at Caltech for Fall 2007. It has updated figures and exercises, but no changes in the main text from Version 2.7a.
- 21 Jul 07: We have sent the final body text to the publisher for copy editing and this is now posted on the site as Version 2.7a. Exercises, index and figures are still being worked on, but these are getting much closer to final form. We will be using this version of the text at Caltech in the fall term.
- 1 Jun 07: We have signed a contract with Princeton University Press to publish Feedback Systems. The current plan is for the book to be available in April 2008, in time for adoption for Fall 2008 courses. The PDF files of the book will remain online via this wiki.
