The book by C.T. Chen, "Linear System Theory and Design, 3rd Ed.", Oxford U. Press, 1999, is a very good introduction to the state-space approach to control systems. I used the first edition ("Introduction to Linear System Theory", Holt, Rinehart & Winston,1970) when taking a graduate course in 'Modern' control systems in 1972. The second edition (HR&W, 1984) had its title changed to the current one, and is larger and more mathematical than the 1st and 3rd editions. To appreciate this book you need an elementary but solid grounding in matrix algera and analysis. It is surprising to me that there are so few books on this subject, given its importance. It is also surprising how few people know about linear system theory and state-space methods. Most mathematical physicists that I know are unaware of this subject. Derek O'Connor

Thanks. For some reason, the download failed, but I'll have another try soon. I found a book by Durbin and Koopman, that worked very well. Not very formal on state space as such, but very effective on Kalman filters. I had a working Kalman filter -- implemented from scratch based solely on the text, no algorithm or recipes -- a mere minutes after opening that book the first time. Rune

Hi Rune, On the Internet I ran across a paper on "state space" variables (with some discussion on Kalman stuff), and I thought of you. That paper is at: https://dspace.mit.edu/bitstream/1721.1/831/1/P-0792-06589289.pdf Maybe it's of some use to you, and maybe not. See Ya', [-Rick-]

Hi Rune, When I had "Modern Control Systems" at Santa Clara University circa 1988, we used this text: @BOOK{brogan, title = "{Modern~Control~Theory}", author = "{William~L.~Brogan}", publisher = "Prentice Hall", edition = "second", year = "1985"} I thought it was a good text. Maybe there's something more recent. --Randy

Somebody posted a transcript of Kalman's 1960 paper here: http://www.cs.unc.edu/~welch/kalman/media/pdf/Kalman1960.pdf I suspect the surviving copies of the issue of the journal where the paper first appeared are all but worn out by now. When I looked this paper up in my local library some ten years ago, there were only some poor photocopies of these pages, in an otherwise almost mint condition journal. Rune

I like this book a lot http://tinyurl.com/pbvyh. Its coverage of state-space models is very nice. Basically I buy anything by Kailath or Sayed by default.

Hi all.

A couple of weeks ago, I found a transcript of Kalman's original paper
from 1960. Browsing quickly through it, I found that it was actually
readable, at least with my background in subspace analysis and
linear algebra etc. As far as I could tell, Kalman basically described
null spaces, signal spaces and manifolds 30 years before such terms
became common in the DSP literature. The introductions on Kalman
filters that I have seen before, appear to make an effort to avoid
using
such concepts and terms, achieving little less than obfuscating the
matter even more.

The one problem that seems to be almost unique for the Kalman filter
seems to be that its derivation seems to rely heavily on the state
space formulation of the filter problem. I don't know much about the
state space formulation except what is said in the book by Proakis
and Manolakis, which is virtually nothing.

Does anybody know of a decent text on state space variables?

Rune
