【Abstract】 The problems of H∞ decentralized control and the tolerance to actuator failure are studied for lange-scale symmetric composite descriptor systems. By exploit- ing a sufficient condition for the existence of a decentralized H∞. controller, for the nominal case as well as for contingent situations characterized by con- trol channel failures, the poles and the H∞ - norm of the closed-loop system can be calculated easily based on certain systems of reduced dimensions. Con- sequently, the tolerance to actuator failure can be easily tested.更多还原
