Zeyuan WANG will defend his doctoral thesis on Wednesday, November 26, 2025: “Distributed Event-Triggered Fault-Tolerant Control of Multi-Agent Systems”

Multi-agent systems enable distributed, flexible task execution, but event-triggered communication, fault propagation, and reliable fault-tolerant control remain challenging. This thesis advances event-triggered control for multi-agent systems, emphasising fault estimation and fault-tolerant cooperation. First, an improved dynamic event-triggered control and communication scheme is developed for leader–following consensus in linear multi-agent systems. A co-design of controller, observer, and triggering mechanism avoids continuous communication and allows adjustable inter-event times, and is extended to leader-following formation control. Second, a distributed joint fault-estimation method with dynamic event triggering is proposed to simultaneously estimate actuator multiplicative/additive faults and sensor faults. The strategy applies to linear and Takagi–Sugeno nonlinear systems, including cases with unmeasurable decision variables, and reduces conservatism versus prior designs. Finally, the thesis presents an active fault-tolerant control scheme based on a dynamic event-triggered mechanism. By employing virtual actuators and virtual sensors, consensus control is achieved under intermittent communication environments in the occurrence of faults.
