摘　　要：对电传飞机伺服作动系统各组成部分的非线性及其对系统性能的影响进行了分析、研究,以某型机平尾伺服作动系统为例,建立了伺服作动系统的非线性模型,在Matlab的Simulink中进行仿真分析并与实际响应曲线进行对比,证明了该模型的准确性,为伺服系统非线性模型的建立提供了一套切实可靠的方法。This paper presents analysis and studies on non-lineafity of all constitutes of servo-actuating system on fly-by-wire aircraft and its influence on system performance. It takes the servo-aetuating system of a horizontal tail on a certain type of aircraft as an example to build the non-linearity model for servo-actuating system. Simulation analysis in Simulink of Matlab and comparison with the actual response curve has been conducted to prove the correctness of this model so as to provide feasible and reliable methods to build non-linearity model for servo system.
