摘要: 一、原理和方法 在电传飞行控制系统的设计过程中,往往会遇到由于伺服机构传动中的非线性(如间隙和死区)引起整个系统在某些飞行状态下产生极限环振荡,它是一种0.5~1.5Hz左右的低频振荡,使驾驶员位置处的法向过载的振荡幅值超过±0.05g,不能满足有人驾驶飞机的技术要求。

Abstract: In order to eliminate limit cycles of an aircraft flight control system, a linear model following scheme is adopted in this paper .It presents theoretical analysis and simulation results of this approach which shows that the linear model following approach can eliminate limit cycles of theaircraft flight control system effectively.
