Robust H∞ Reliable Guaranteed Cost Control for Delta Operator Uncertain Systems

This paper is concerned with the problem of guaranteed cost robust H-infinity reliable control for delta operator formulated uncertain systems with actuator failures. Based on the pattern of actuator continuous failures, a sufficient condition of the existence of guaranteed cost controller of delta operator system with H-infinity performance constraints is derived in terms of linear matrix inequality (LMI) approach. When this LMI is feasible, the parameterized representation of the desired state feedback controller is also obtained.
