The Position Servo Control Strategy of High Dynamic Response Based on Electric Steering Gear

Abstract:

This paper studies the current loop, velocity loop and position loop controller of PMSM position servo system for Electric steering gear servo system. It makes research around the principle of PMSM vector control and three control loop control strategy. The control strategy bases on the principle of vector control of PMSM when id=0 and uses the classic PI control theory. A new method of decouple control for the current of direct axis and cross axis direct is presented. It will overcome the impact of EMF when the motor is working in high dynamic. The system uses the feed-forward control to compensate the position deviation of permanent magnet synchronous motor using in the steering gear. The paper also researches transfer function of feed-forward control of the location, and establishes the feed-forward controller model of the position loop. Simulation results demonstrate the effectiveness of our proposed scheme.
