Finite-time event-triggered fault-tolerant control for a family of pure-feedback systems

作者：

Highlights：

• The finite-time fuzzy event-triggered fault-tolerant tracking control scheme of uncertain nonlinear systems with actuator faults is developed.

• By constructing the proper parameter updated laws, the improved adaptive fault-tolerant control algorithm can guarantee the output tracking error converges to a small neighborhood of the origin in finite time.

• It is proved that the novel fuzzy event-triggered fault-tolerant mechanism proposed in this paper has much wider scope of the applicability than the existing schemes.

• Simulation results of Brusselator model demonstrate the effectiveness and advantages of the presented control method.
