摘要
以内置式永磁同步电动机为研究对象,提出一种具有快速动态响应的前馈弱磁控制策略。根据电机运行时的转矩和定子磁链给定值,通过实时查表得出电机的交、直轴电流参考值;同时为了解决电动机高速运行时参数漂移问题,在前馈控制基础上叠加了基于输出电压的闭环控制策略,有效地提高了系统的鲁棒性。实验结果证明电动机在全速范围弱磁控制策略的有效性。
Presented an algorithm of interior permanent magnet synchronous motor in the field-weakened region, by combining closed-loop control using the output voltage and feed-forward control with the precalculated tables, the proposed strategy could achieve fast dynamic control as well as parameter insensitivity in the field-weakening region. Results of the experiment indicated validity of the field-weakening method which introduced in the paper.
