液压助力式飞行操纵系统仿真分析

以某型水陆两栖飞机液压助力式飞行操纵系统的设计为背景,采用Matlab/Simulink建立液压助力式飞行操纵系统的动力学模型,该模型考虑了支座间隙、滑阀遮盖、摩擦力等非线性因素.通过仿真分析得出飞行操纵系统的各项性能指标,包括峰值时间、调节时间、超调量、相位滞后、流量需求等,以及各性能指标对主要设计参数的敏感性,为后期的铁鸟试验及优化设计提供参考.

Simulation and Analysis of Hydraulic Booster Flight Control System

In the process of a mechanical-hydraulic flight control system design,a dynamic model of the flight control system is built by using Matlab/Simulink,which considers nonlinear factors such as backlash,slide valve covering and friction.Based on the Simulink model,lots of performance data are estimated,including peak time,settling time,overshoot,phase lag,flow demand,and the sensitivity of performance data to main design parameters are analyzed,which provides reference for the late Iron Brid test and optimal design.
