摘要

本文提出了鲁棒预测电流控制(RPCC)以实现永磁直线同步电机(PMLSM)驱动的高电流环性能。首先，提出了一种无差拍电流预测算法，推导了永磁同步电机的预测控制模型。其次，对算法的稳定性进行了分析，得到了算法的稳定条件。采用鲁棒控制方法，使控制算法在电机参数不匹配范围内保持稳定。最后，在TMS320F28335 DSP实验平台上进行了物理实验。实验结果表明，该算法具有较好的动态性能和鲁棒性。实验结果验证了该方法的正确性和有效性。

Robust Predictive Current Control for Permanent Magnet Linear Synchronous Motor Servo System

This paper presents robust predictive current control (RPCC) to achieve high current-loop performance for permanent magnet linear synchronous motor (PMLSM) drives. Firstly, a deadbeat current predictive algorithm is proposed and the predictive control model of PMLSM is derived. Secondly, the stability of the algorithm is analyzed and the stable condition of the algorithm is obtained. A robust control method is adopted to make the control algorithm stable in the range of motor parameter mismatch. Finally, physical experiments are carried out on the TMS320F28335 DSP experimental platform. Experimental results show the proposed algorithm has better dynamic performance and robustness. The correctness and effectiveness of the proposed method are verified by experimental results.
