英文摘要
      By analyzing more common failure models of actuators and sensors,the observer based H-infinity reliable controller design problem for descriptor systems is studied.Using generalized algebraic Riccati inequalities（GARI）with constraints,the sufficient and necessary condition,as well as the design method that there exists H-infinity reliable controller for descriptor systems is obtained in the case of actuator failures.Meanwhile,the design method and sufficient condition where there is an (H-infinity) reliable controller for descriptor systems is obtained in the case of sensor failures.Due to the designed H-infinity reliable controllers,the resulting closed-loop descriptor systems are admissible and have H-infinity performance.Simultaneously,the GARI with constraints are transferred into linear matrix inequalities (LMI),and therefore,the design approach of H-infinity reliable controller for descriptor systems is reduced.
