Abstract:The problem of robust H-infinity fault-tolerant control system design for nonlinear uncertain time-delay systems with actuator failures is addressed. A more practical and general model of actuator failures is adopted. Based on linear matrix inequality approach, the consistency theory on robust stabilization index and H -infinity index for nonlinear uncertain time-delay systems is set up. Furthermore, sufficient conditions for the existence of robust H -infinity fault-tolerant controller is given in terms of LMIs. A simulation example shows the efficiency and necessity of the design method.
Keywords:Fault-tolerant control  Robust control  Consistency  Time-delay systems  Actuator failures
