主动侧杆系统多余力机理及敏感性分析OA

In the active sidestick system,there is a problem of surplus force,which causes problems such as'jigging rod beater',poor situational awareness,and easy to induce flight accidents under special circumstances.The parameters associated with the surplus force of the system were first identified through theoretical analysis.The influence of each parameter on the surplus force of the system was then thoroughly examined through Monte Carlo simulation.Based on the results of the Monte Carlo simulation,the spectrum analysis of the surplus force and the sensitivity analysis of the influence of the surplus force of each parameter were conducted in order to better understand the mechanism of the surplus force and determine the influence mechanism and law of the system parameters on the surplus force.The driver's control frequency,the equivalent inertia of the sidestick,the equivalent damping of the sidestick,the signal bias of the speed sensor,and the signal bias of the torque sensor are among the factors that have the biggest effects on the surplus force of the system.The degree to which each parameter influences the surplus force is determined through qualitative and quantitative analysis,which serves as a guide for the design and compliance verification method of the surplus force suppression method of the active sidestick system.
