摘　　要：针对大功率永磁同步电机(PMSM)传动系统对低开关频率和共模电压抑制的需求,提出一种柔性多目标预测控制策略。采用复合电流边界限定的方法实现对电流跟踪、开关频率和共模电压的协同控制。所提方法运算量低,参数设计简单。搭建了4.4kWPMSM传动系统实验平台,实验结果验证了所提控制方法的有效性。Aiming at the low switching frequency and common-mode voltage suppression requirements in the drive system of high-power permanent magnet synchronous motor(PMSM),a flexible multi-objective predictive control strategy is proposed.The method of composite current boundary limitation is used to realize the coordinated control of current tracking,switching frequency and common-mode voltage.The proposed method has low computational effort and simple parameter design.A 4.4 kW PMSM drive system experimental platform is built,and the experimental results verified the effectiveness of the proposed control method.
