Abstract

This paper proposes a method that based on direct thrust control (DTC) to address the disturbance rejection problem in permanent magnet linear synchronous motor (PMLSM). In view of the PMLSM, direct torque control design is suitable for the DTC of linear motor control system. According to the rated load capacity of the motor, we give PMLSM a load disturbance. Then we obtain the motor dynamic characteristics which are analyzed from the simulation. Finally, the simulation results show that: the PMLSM control system that based on DTC has stronger robustness and better performance of disturbance rejection.
