摘　　要：针对具有作动器故障的飞行器,本文提出了一种基于子控制器最优组合的Youla参数化容错控制器。该方法根据Youla参数化理论设计标称控制器,设计了一种能够提供作动器的故障信息的故障重构算法,并且构造出可以利用故障信息进行对设计的容错控制器进行在线调整的可重构的子控制器最优组合参数化矩阵。仿真结果表明,所设计的容错控制器可以有效地镇定故障飞行器,保证飞行的安全可靠性。This paper proposes a Youla parameterized fault-tolerant controller based on the optimal combination of sub-controllers for aircraft with actuator failure.This scheme designs the nominal controller based on Youla's parameterization theory,proposes a new fault reconstruction algorithm to provide actuator fault information,and presents a reconfigurable sub-controller optimal combination parameterization matrix.The parameterization matrix adjusts the designed fault-tolerant controller.The simulation results show that the designed fault-tolerant controller can effectively stabilize the malfunctioning aircraft,thereby ensuring the safety and reliability of flight.
