摘　　要：分析了出现喷口分油活门位移传感器故障时,通过开环设置电液伺服阀电流控制喷口面积存在的问题,在此基础上提出了一种容错控制方法,根据喷口面积期望值与实际测量值之间的误差闭环运算喷口控制电液伺服阀电流。通过全数字仿真和半物理模拟试验对该容错控制方法进行了验证,结果表明,该容错控制方法能够保证全权限数字电子控制系统稳定工作,并具有较好的稳态和动态性能,且实施方便,对提高航空发动机全权限数字电子控制系统的工作可靠性具有重要作用。The problems of the method of controlling the aeroengine nozzles by setting the electric-hydraulic servo valve current in an open-loop when oil separator valve displacement sensor fails are analyzed,and the fault tolerant control method of aeroengine nozzle actuators is proposed.This method set the electro-hydraulic servo valve current through the results of a closed-loop operation,which used the error between the demand and feedback of the nozzle area.The fault tolerant control method was verified by full-digital simulation and semiphysical simulation experiments.The results showed that the fault tolerant control method can essure the stable operation of full authority digital electronic control(FADEC)systems and has good steady-state and dynamic performance,and is easy to implement.Therefore,it plays an important role in improving the reliability of aeroengine FADEC system.
