Application of PID Control Algorithm Based on BP for Permanent Magnet Linear Servo System

In view of the characteristics of nonlinear,multi-variable,strong coupling and uncertain model structure for the permanent magnet linear synchronous motor(PMLSM),a self-tuning proportional integral derivative(PID) algorithm based on back propagation(BP) neutral network(NN) is proposed.The simulation research using MATLAB soft is done with this control strategy applying in PMLSM.The simulation results show that this method is much self-adaptive,higher control accuracy and a stronger robustness.
