Modelling and tolerant control of the time-delay networked control system based on pole configuration

Abstract

For networkeded control systems with time delays, while considering the influence of external disturbances, a criterion is derived to ensure that the actuator is robust when a fault occurs, and a robust $H_{\infty}$ fault-tolerant controller design method is given. A fault diagnosis system is designed and fault-tolerant control is implemented using the closed-loop poles as fault information. The closed-loop system poles are used as input to an Extreme Learning Machine (ELM) fault diagnosis model to achieve fault-tolerant control of the different channels of the system actuator. Finally, a simulation example is used to verify the effectiveness of the described method.
