Design and Research of Electric Control Load System of Flight Simulator

Abstract

The control load system is a human sense system, which simulates the sense of control force of the driver under different environmental conditions. According to the analysis of aircraft control system, gives a simulation of a certain type of flight simulator control loading system principle, build a digital electric control load system. The control strategy of the electric torque servo system, which is combined with the control of the closed loop PID control, the current loop control and the surplus torque compensation, is used in the flight simulator control system. The simulation results show that after adding the closed-loop controller and the current loop control, the overshoot of the system decreases and the following performance is better. The surplus torque is reduced by 95%. Actual control effect shows that the double loop combined with extra torque compensation of compound control can effectively reduce the surplus torque disturbance and control the system steady error. The research can provide theoretical basis for the prototype of the load system of flight simulator.
