The Construction and Validation Studies on Principle Prototype of Electric Force-feeling Simulation System

In order to improve the control loading fidelity of helicopter flight simulator force-feeling simulation system, this paper develops the principle prototype of force-feeling simulation system, establishes the electro-motive force servo loading system model, applies the model to the force-feeling simulation system principle prototype and conducts the test of sense of force. The results show that the design of force-feeling simulation system is reasonable, using the model of force temporal tracking and force displacement trajectory tracking to study the sense of force tracking performance. The control algorithm also shows that: conventional PID control is hard to satisfy the real-time accurate tracking for model of force. To improve the tracking speed and precision, feed-forward compensation with PID control and feedback-feedforward iterative learning control strategies should be used.
