Force modeling and control of servo motor control loading system in flight simulator

Control loading system is a device to provide pilots with rudder force feedback in flight simulator. In those systems of pilot and aircraft information interaction, control loading system gives the pilots the most intuitive information of the aircraft status. Among them, the servo motor control loading system has been used more and more because of its compact structure and superior control performance. In order to manipulate the realistic simulation of force in the load system, the model of the control loading system is proposed in this paper, and the PID controller is used to control the force servo system. The model is divided into two parts, one is the load model of the aircraft rudder to the handle, and the other is the torque model of the motor. On the basis of this, a Simulink simulation model is proposed. The simulation results show that the vibration caused by external disturbance and the delay caused by the control loading system itself have a nice inhibition effect.
