Adaptive fuzzy event-triggered fault-tolerant control of switched
nonlinear systems with actuator failures under state-dependent
In this paper, an adaptive fuzzy event-triggered control (ETC) problem
of switched nonlinear systems (SNSs) under actuator failures is studied.
Fuzzy logic systems (FLSs) are introduced to approximate the unknown
nonlinear terms of the system. To reduce the wastage of communication
resources (WCRs), an adaptive fuzzy event-triggered mechanism (ETM) with
a state-dependent switching law is designed. In order to ensure the
stability of whole systems, the convex combination technology is
adopted. The dynamic surface control method is employed to deal with the
problem of ‘curse of dimensionality’. Additionally, a single Lyapunov
function is constructed to analyze the stability of the system. It is
proved that all signals of the closed-loop system (CLS) are bounded.
Finally, the effectiveness of the method is verified by simulation
