Abstract

This paper discusses the implementation of an LQ controlstrategy through the use of a Minimal Control Synthesis adaptivealgorithm recently presented in the literature. It is shown thatby using such approach the structural stability of the closed-loopsystem can be improved with respect both parameter mismatches andnonlinear perturbations. A case study discussed in the literatureon LQ controllers is used to illustrate the strategy presented inthe paper.
