考虑执行器退化的容退控制器设计
Design of Tolerance-Degradation Controller Considering Actuator Degradation
摘要
Abstract
The actuator will gradually deteriorate before a failure occurs,and the degree of degradation of the actuator directly affects the performance of the control system.The existing research mainly focuses on the fault-tolerant control of actuator faults.Therefore,it is necessary to study the tolerance control strategy considering the degradation process of the actuator.This paper took the linear system as the object.Firstly,the system dynamic model and the actuator degradation model considering the mutual influence between the system state and the actuator degradation state were established.Then,based on this model,a tolerance-degradation controller was designed.Furthermore,the state observer and the Kal-man filtering algorithm were jointly utilized to estimate the system states and degradation states.The experimental results show that the tolerance-degradation controller can ensure the stability and optimal per-formance of the control system during the actuator degradation process.关键词
