Adaptive Event-Triggered Fault-Tolerant Control for Networked Multi-Agent Systems under Actuator and Sensor Faults

This paper proposes a networked active fault-tolerant predictive control strategy based on an adaptive event-triggered mechanism for networked multi-agent systems subject to simultaneous actuator and sensor faults. First, a state and fault estimator is designed to estimate the system states as well as the actuator and sensor faults under the double-fault scenario. Second, an adaptive event-triggered mechanism is developed to reduce the communication frequency and alleviate the communication burden of the system. Then, a fault-tolerant control law is constructed to achieve active fault-tolerant control for multi-agent systems with double faults. Finally, a delay compensator is introduced to address the network-induced delay problem. The proposed strategy effectively compensates for communication delays and reduces the occupation of network resources.
