Description of the course |
| Polynomial methods for
robust control |
Didier Henrion, LAAS CNRS Toulouse, France |
Universidad de los Andes, Merida, Venezuela, October through November 2001 |
A course for graduate students or researchers with a background in linear control
systems, linear algebra and convex optimization. The course focuses on the use of polynomials
and polynomial matrices for the analysis and design of linear systems affected by parametric
uncertainty. |
| Polynomial Methods for Control Analysis and
Design |

Polynomials and polynomial matrices play an important role in linear system theory, from
first principles multivariable linear systems are modelled by sets of differential equations in
the input u and the output y of the form D(d/dt)y(t) = N(d/dt)u(t). D and N are polynomial
matrices in the differential operator d/dt. Polynomial matrix models do not replace state space
and frequency domain descriptions but provides a powerful additional tool.
The course shows how to systems may be analyzed and manipulated using this approach based on
the mathematical properties of polynomial matrices. Many of the characteristics of polynomial
matrices are reviewed, such as canonical and reduced forms, elementary operations and
unimodular polynomial matrices, and divisors, primness and factorization.
The closed-loop properties of single-input single-output and multivariable systems may
conveniently be analyzed using polynomial matrix theory. It is only a small step from stability
analysis to the pole assignment problem. The pole assignment problem is intrinsically linked to
linear polynomial matrix equations of the form DX + NY = C in the unknown polynomials or
polynomial matrices X and Y. This crucial equation is extensively discussed.
Polynomial methods lend themselves very well to the frequency domain solution of famous and
proven control system design methods such as LQG, H2 and deadbeat. These approaches to control
system design and their application are thoroughly reviewed.
Whenever appropriate the Polynomial Toolbox 2 for MATLAB will be used for on-line illustrations
and demonstrations. Copies of the slides will be made available to the participants. |

The course presents "classical," "modern" and "post modern" notions about linear control
system design. First the basic principles, potentials, advantages, pitfalls and limitations of
feedback control are presented. An effort is made to explain the fundamental design aspects of
stability, performance and robustness. Next, various well-known classical single-loop control
system design methods, including Quantitative Feedback Theory, are reviewed and their strengths
and weaknesses are analyzed. Likewise, LQ, LQG and control theory and some of their extensions
are reviewed. Their potential for single- and multi-loop design is examined. The course
includes a survey of design aspects that are characteristic for multivariable systems, such as
interaction, decoupling and input-output pairing. After a thorough presentation of structured
and unstructured uncertainty model design methods based on H-infinity-optimization (in
particular, the mixed sensitivity problem) and mu-synthesis are presented. |
