摘要：This paper deals with a major problem related to the modern control systems, which is the fault-tolerant control. Firstly, a novel fault-tolerant control method for systems with multi actuator and parameter faults is proposed. The fault-tolerant controller is synthesized by using the Lyapunov function and a linear matrix inequality approach. The novelty of the present study resides that the fault estimation is not necessary and especially for systems with complex multi-fault.The only fault diagnosis module based on Luenberger observer is used for residual generation which is injected into the control loop. Next, based on the fault diagnosis results, a new fast fault-tolerant controller is designed for aims to construct a reconfiguration block and to achieve some prescribed specifications.Finally, the proposed fault-tolerant control technique is applied to the vertical take-off and landing (VTOL) aircraft system which demonstrates the effectiveness of the developed techniques.
