✦ Synopsis

Two methods of simulating continuous-data systems by sampled-data models are presented. Sample-andhold devices are inserted in an otherwise continuous-data system, and the input and the feedback gains are modified to make the response of the sampled-data model as close to that of the original system as possible. A point-by-point comparison method matches the state variables of the two systems at the sampling instants. Another method relies on the optimization of the sampled-data system with a quadratic performance index.

This paper considers the problem of constructing a controller which quadratically stabilizes an uncertain system and minimizes a guaranteed cost bound on a quadratic cost function. The solution is obtained via a parameter-dependent linear matrix inequality problem.
