Aiming at the current error caused by parameters disturbance and model mismatch, a robust predictive current control(RPCC) with internal model disturbance observer(IMDO) is proposed to achieve high accurate current control of permanent magnet linear synchronous motor(PMLSM) drives. Firstly, a deadbeat current predictive control algorithm based on the mathematical model of permanent magnet synchronous linear motor is constructed, and the stability domain of the algorithm is obtained. Thereby, the control alg...
