Reliable robust H∞ control for uncertain systems with input constraints

This paper investigates the problem of robust H∞ control for parameter uncertain systems with input constraint. For the admissible parameter uncertainty, a reliable output feedback controller is designed, which can guarantee the closed-loop system to satisfy the system design requirements. A sufficient condition for the existence of the reliable robust output feedback controller are given in terms of liner matrix inequalities (LMIs), and the controller design is cast into a convex optimization problem subject to LMI constraints. Simulation results are given to illustrate the effectiveness of the proposed design method.
