Abstract
This paper is concerned with the issue of platoon fault-tolerant control of the system with time-varying actuator faults. By obtaining the relative state information of neighboring vehicles, two event-triggered fault-tolerant controllers are designed for the two cases of the leader vehicle speed. Then the vehicle platoon system is transformed into error system, and the event-triggered control strategy is designed, in an effort to further save resources. Moreover, by the related theory of Lyapunov, it is shown that the error system is bounded. Finally, two simulation examples are given to show the effectiveness of the proposed approach.

Summary
The automatic driving of vehicle formation can improve the road utilization and alleviate the traffic congestion effectively. W. Wang et al.: Fault-Tolerant Platoon Control of Autonomous Vehicles Based on Event-Triggered Control Strategy was presented in [11]- [12] and a novel platoon model was established in [13]. A distributed adaptive control strategy to compensate for the effects of actuator failure and model uncertainty on MASs was studied in [26]. Combining the event-triggered algorithm with the intelligent vehicle fault-tolerant control problem will have great research significance. Unlike the literature employing the FTC methods, a novel event-triggered fault-tolerant controller is proposed for the platoon model with time-varying actuator faults.
