摘要
研究了一种基于TMS320LF2407A为控制芯片的永磁同步电机(PMSM)调速系统,分析了其控制策略。将预测控制方法应用于PMSM的闭环控制,以固定频率采样定子电流,按电机模型计算出下一采样时刻逆变器的最优控制电压矢量,从而通过预测下一时刻实际定子电流去追踪下一时刻参考电流。与现有预测控制方法相比,该方法具有对PMSM模型的精度要求低、系统算法简单和鲁棒性强的特点。
A Permanent Magnet Synchronous Motor drive based on TMS320LF2407A was discussed and its control strategy was also analyzed. The predictive control method is used in regulation system of PMSM to fix the stator current with constant frequency. According to the motor-model, optimum-controlled voltage vector is computed at the next sample moment to control the actual next stator current so as to follow the next reference. Compared with the existing predictive control method, the proposed one only needs low precision model to PMSM speed control with the characteristic of simple system algorithm and strong robustness.
