Study of Thrust Lever Control Loading System in Flight Simulator
Abstract
Aiming at computing the force feel to be simulated at real time, thrust lever control loading system’s simulation model is set by software called SimMechanics after its control mechanism being analyzed. The dynamic characteristics of control systems and model torque are studied based on the simulation model. Then the counter potential, primary element to cause the surplus torque, is pointed out according to the dynamic characteristics of control. To make the loading system not only flow the model torque precisely but also retrain surplus torque effectively, the low frequency of the current loop is designed due to frequency spectrum of counter potential and follow-up component in model torque, while the medium frequency is on basis of the step component in model torque. Finally, the reasonableness of the designed current loop is verified by computer simulation of the torque output by motor and loading torque.
