摘　　要：某型四余度液压舵机是某型飞机平尾操纵系统的关键部件。详细研究了某型四余度液压舵机单通道伺服控制系统在正常状态和3种典型的故障状态下的输出特性,并进行了仿真试验研究。仿真试验结果表明,在这3种典型故障状态下,液压舵机伺服控制系统无法对各种给定信号(期望输出)实现有效的跟踪。研究工作为深入了解该型舵机的工作原理、工作过程和输出特性提供了依据。One four redundant hydraulic actuator is a pivotal component of one aircraft＇s horizontal tail steering system.The output characteristic of normal state and three typical fault states for hydraulic actuator servo control systems with single channel and four re-dundancies was researched in detail.The simulation test and research were carried out.The simulation test results show that hydraulic actuator servo control systems can not implement tracking of all the input signals （ anticipant output） effectively under the circumstances of three typical fault states.The research work can provide a massive base to understand the work principle, the work course and the output characteristic of the hydraulic actuator.
