Robust Adaptive Switching Fault-Tolerant Control of a Class of Uncertain Systems against Actuator Faults

摘要: This paper deals with the fault-tolerant control (FTC) problem for a class of linear time-invariant systems time-varying actuator faults and uncertainties. For more general consideration, uncertainties are supposed to depend on states unknown constant bounds. sake eliminating effects such state-dependent automatically, switching strategy which is formulated by sign function designed configure controller based system’s states. And some adjustable parameters updated via designing adaptive laws. Based information from estimation mechanism, robust controllers constructed compensate Through Lyapunov functions schemes, asymptotic stability resulting FTC uncertain system can be achieved. The effectiveness proposed design illustrated rocket fairing structural-acoustic model.
