A fuzzy fault-tolerant control method based on an event-triggered mechanism is proposed for a truck-trailer system with time delays, external disturbances, and actuator faults.Considering the characteristics of actuator faults, the truck-trailer system, which includes time delays and external disturbances, is modeled using the T-S fuzzy mathematical model. The event-triggered mechanism is introduced in the design of the fault-tolerant controller to reduce system energy consumption. The Lyapunov-Krasovskii functional is then used to derive a stability criterion that ensures system H∞ performance, and the controller gain matrix is obtained in the form of linear matrix inequalities. Simulation results show that the proposed controller effectively improves the system"s dynamic performance and fault tolerance while reducing resource utilization.
