PID Iterative Fault-Tolerant Control for Continuous Time-Varying System with Actuator Fault
摘要
Abstract
A convergence condition of Proportion, Integral and Derivative(PID)iterative learning fault-tolerant controller is proposed for linear time-varying system with actuator fault. An open-loop PID iterative learning fault-tolerant controller is designed for time-varying repeat system, and a sufficient condition for the existence of the PID controller is analyzed based on λ-norm. The convergence condition of PID fault-tolerant controller is changed as Linear Matrix Inequality(LMI) based on Schur complement principle, under the presetting iterative learning convergence rate, the optimal control gains can be determined by using LMI, it avoids the blindness of the iterative control gain settings. The numerical simulation of rotational control system verifies the ability of fault tolerance and tracking performance of PID iterative fault-tolerant controller.关键词
