飞行模拟器电动式操纵负荷系统控制策略

操纵系统的控制策略是力伺服系统加载的关键技术。以电动式力伺服系统为加载方式的飞行模拟器操纵负荷系统，采用上位机力闲环PID控制、电流环PI控制与多余力矩补偿相结合的策略实施控制。仿真结果显示：分别加入力闭环和电流环控制后，系统的超调量减小，跟随性能较好；采用角速度力矩补偿法，系统多余力矩下降了90％。实际控制效果进一步表明，双环与力矩补偿相结合的复合控制策略可有效减小系统多余力矩，控制稳态误差。该研究可为构造操纵飞行模拟器负荷系统样机提供理论依据。

Control strategies of electric powered control loading system in flight simulator

The control strategies of control system hold the key technologies of force servo system loading. This paper proposes control strategies consisting of adoption of electric powered force servo system as loading mode of the flight simulator control loading system took, introduction of upper monitor force closed-loop PID control, and combination of current loop PI control with combination of surplus torque compensation. The simulation results indicate that addition of force closed-loop and current control gives the system the smaller overshoot and better tracing; adoption of angular velocity torque compensation affords a 90% decrease in surplus torque. The actual control further shows that the control strategies combining double loops torque compensation allow an effective reduction in surplus of the system and better control of steady-state error. This research provides theoretical basis for constructing control loading flight simulator system model.
