摘要：
This paper presents the integrated fault-tolerant control scheme for nonlinear system with multi-fault. After the unknown faults are estimated online by using the fuzzy credit assignment CMAC (FCACMAC), the effective control law reconfiguration strategy based on the sliding mode control technique is used to compensate for the effect of multi-fault. For multiple faults scenarios and three-tank system, the proposed fault-tolerant controller adjust its control signal by adding a corrective sliding mode control signal to guarantee the system stability, and numerical simulations demonstrate the effectiveness of the proposed sliding mode fault-tolerant controller.
