英文摘要：
For uncertain nonlinear systems under the conditon of actuator failures, the problem of robust guaranteed cost controller design with L2-gain disturbance attenuation performance constraints is studied. A more practical and general model for actuator failures is put forward, and the concept and properties of robust guaranteed cost control system with L2-gain disturbance attenuation performance are also presented. Furthermore, based on Hamihon-Jacobi-Isaacs inequalities approach, a sufficient condition is given, under which the closed-loop system with actuator failures is asymptotically stable with given anti-disturbance performace and the cost function owns an upper bound. A simulation example shows the efficiency of the design method.
