电动操纵负荷系统俯仰通道参数整定研究

Study on parameter tuning in control loading system of flight simulator

电动操纵负荷系统是飞行模拟机的重要组成部分,用于向飞行员提供逼真的力感模拟.当需要控制操纵负荷系统的作动器时,通常按照相关的机构(控制杆)把控制器放在电机驱动器做一个模型,然后整定控制参数.然而,开发操纵负荷系统时,有时并不知道机械机构的参数.这意味着建立操纵负荷系统的模型是困难的,因此需要有效的方法解决操纵负荷系统的系统控制参数整定问题.文中论述了一种基于波德图的有效的飞行模拟机操纵负荷系统的参数整定技术.

Electric control loading is one of the most important parts of a flight simulator because it realizes the real flight control environment. When the actuator of CLS are controlled, generally the controller are put into motor drive and make modeling related to the mechanism （control stick） and then tune the control parameters. However, there are not the parameters of the mechanism （control stick） exactly in developing CLS. It means the modeling of CLS to be difficult. Therefore, there need the way to theoretically and quantitatively find out the parameters of the actuator controller of CLS , In this paper, a systematic and effective tuning technique are presented for the control loading system based on Bode plots.
