驾驶员诱发振荡的抑制方法

对电传操纵系统驾驶员诱发振荡（ＰＩＯ）的现象进行了分析，指出了舵回路速率饱和是造成ＰＩＯ的主要原因，并有针对对给出了一种非常规的用于解决饱和非线性问题的程序控制方法。这种方法主要是通过舵回路反馈的状态信息来改变驾驶杆输入信号的放大系数，从而达到有效抑制ＰＩＯ的目的，同时用Ｈｕｒｗｉｔｚ稳定判据进行了机理分析，最后给出了仿真验证结果，证明该方法是简单而有效的。

A Restraint Way of Pilot Induced Oscillation

This paper analyses the phenomenon of the pilot induced oscillation of flight by wire system,and points out that actuator rate limit is the main reason to lead to PIO.For this reason,this paper gave out a non conventional control methods for flight control system.This way can be used to solve the problem of saturation nonlinear.This method mainly used a feedback information got from the steer wheel loop to change the gain of the steer stick input signal , so that it can restrain PIO effectively. In the later , this paper analyses the control mechanism of the method by using Hurwitz stable criterion and gave out the results of imitation.
