In maglev long-stator linear synchronous motor drive systems, multiple sources of disturbances during their operation can lead to significant fluctuations in motor parameters, thereby reducing the control effect of model predictive approaches. To address this issue, a robust predictive control algorithm based on error feedback correction is proposed. Under this strategy, the error between the predicted and measured values of current is used as a feedback signal. By designing an appropriate feedback structure to adjust the output voltage of the conventional deadbeat predictive controller, the proposed method can effectively mitigate steady-state tracking errors and instability problems caused by mismatches in inductance, resistance and flux linkage. Finally, a maglev linear synchronous motor platform was constructed for comparative verification, and experimental results validated the effectiveness of the proposed algorithm.
