Abstract:This paper addresses the problem of eventbased adaptive fault estimation (FE) and fault-tolerant control (FTC) for a class of strict-feedback nonlinear systems with full state constraints. The unknown fault and the to-be-tested states of the system are estimated by an innovative adaptive fault observer based on a modified intermediate variable update law with fault switching function. In addition, an event-triggered mechanism and adaptive fault-tolerant controller co-design scheme is proposed according to back… Show more
