Enhancing the structural stability of LQ optimal controllers via the MCS adaptive algorithm

This paper discusses the implementation of an LQ control strategy through the use of a Minimal Control Synthesis adaptive algorithm recently presented in the literature. It is shown that by using such approach the structural stability of the closed-loop system can be improved with respect both parameter mismatches and nonlinear perturbations. A case study discussed in the literature on LQ controllers is used to illustrate the strategy presented in the paper
