摘要
This brief studies the control problem for nonlinear systems with uncertain actuator failures and input quantization. First, a hysteretic quantizer is applied to reduce chattering in the quantized signals. Then, using the backstepping technique, a finite-time fault-tolerant controller is designed. In addition, the control input is quantized by the hysteretic quantizer. It is proved that the global finite-time stability can be ensured for the nonlinear systems with uncertain actuator failures and quantized input signals. Finally, the simulation example of the hydraulic system is presented to verify the established control method.
