Robust Position Tracking Control of The Linear Switched Reluctance Machine Motion System

This paper addresses the position tracking control problem for a linear switched reluctance machine (LSRM) motion system based on proportion-integral-derivative (PID) parameters tuning method. The closed-loop control model of the LSRM motion system is built by MATLAB/simulink. The controller and model parameters can be obtained and modified online by dSPACE real-time simulation system platform. The stability conditions and the precise PID position controller design method for LSRM are proposed by Lyapunov stability theory. Several experiment results are presented to verify the effectiveness of proposed model for the LSRM motion position tracking control system. The maximum position error is less than 0.16mm, and the experiment results show that the LSRM motion control system has good robustness.
