Sliding Mode Control of PMLSM for high Speeding Gringding Machine

摘要：

Permanent magnet linear synchronous motors (PMLSM) offer several advantages over their rotary counterparts in many precision manufacturing applications requiring linear motion, which can achieve a much higher speed and a higher position accuracy. However, linear motors are more sensitive to disturbance and parameter variations. Furthermore, the linear motor systems are subject to significant nonlinear effects due to friction and force ripple. A sliding mode controller with an adaptive disturbance observer is processed to achieve high accuracy in the presence of external disturbance and parameter uncertainty. The position control for the gringding machine of a PMLSM feed drive using the proposed control strategies is illustrated. Simulation results show that the proposed controllers provide highperformance dynamic characteristics and are robust with regard to external load disturbance.
