Fault Estimation and Observer-Based Fault-Tolerant Control for Multi-Agent Systems with time-delay
Jianliang Chen, Xin Liu · 2023
This paper investigates the problem of fault estimation and fault-tolerant control for nonlinear multi-agent systems with time-delay, actuator faults, sensor faults. First, a fault estimation observer is designed to achieve the estimation of actuator faults and sensor faults. Second, a feedback controller based on observer is used to compensate the effect of faults and disturbances. Third, the linear matrix inequality is applied to obtain sufficient conditions for observer and controller. Finally, the effectiveness of observer and controller is verified by one example.
