Abstract :
This paper describes a robust analysis and design method for LQ optimal control. Based on the results of [1] and [2], the largest permissible regions in the complex plane for the open-loop poles are obtained to maintain the system´s LQ optimality under changes in system parameters. The matrix inequalities for determining the regions are given in this paper. In this method, the feedback and weighting matrices can be modified to design for a robust closed-loop optimal system.
