Research and Design of Adaptive Fault Tolerant Control Based on Actuator Faults

in this paper, we study the fault tolerant control problem of actuator fault by indirect adaptive method. There are normal conditions, the failure of executor partial, interruption, and non-parametric failures of actuator form. We assume that the efficiency factor of actuator is unknown, furthermore, the external disturbances and the boundary of time-varying card failures are also unknown.In addition, compensate the actuator failure and external disturbance by designing the adaptive controller. The asymptotically stable of adaptive closed-loop system can be guaranteed whether under normal operation or under the influence of fault and disturbance based on the Lyapounov theory. And the method is proved to be effective by the simulation example.
