- Classical Control Using H-infty Methods
- By J. William Helton and Orlando Merino. SIAM, 1998.

This is a research monograph which focuses on measurement feedback control or, for those with less of an engineering pursuasion, on factoring nonlinear operators acting on L^2. It gives an outline of the subject and then it gives details of resesarch (mostly of the authors) over the last 4 years. The first part of the book should be good for the beginner and the book's interior is definitely on the bleeding edge. The lighthearted part is:
- Extending H-infty Control to Nonlinear Systems.

Software
The following software packages are currently available through anonymous ftp.
| NCAlgebra |
|---|
Our Non Commutative Algebra Package which runs under Mathematica is available from mathsource.wri.com or better yet from the NCAlgebra Homepage. Getting it from us is better since our version is much more recent. A Noncommutative Gröbner Basis Package NCGB which makes use of the NCAlgebra package is available too NCAlgebra Homepage. It uses a link to C++ which makes it delicate, so as of April fools 1999 we support it under Solaris operating systems only. For complaints or to report really wild NC Expereiences there is our email ncalg@ucsd.edu.
| Optimization Over Analytic Functions |
|---|
There are several software packages available for optimization over analytic functions which were used to run examples in the book Classical Control Using H-infty Methods.
