电动汽车用异步电机弱磁控制综述
|
摘要
为满足纯电动汽车对宽调速范围的要求,文章分析研究了纯电动汽车用异步电机弱磁控制策略的研究现状,详细阐述了不同坐标系下异步电机的数学模型及矢量控制策略,并对宽调速范围区间进行了分类,综合比较了异步电机传统和新型弱磁控制策略的性能优点及存在的问题,研究结果表明,传统1/ωr弱磁策略适用于性能要求不高的异步电机驱动领域,而变期望电压弱磁控制策略在电动汽车上有较好的应用优势。
In order to meet the requirements of the wide speed range of the pure electric vehicle,the current situation of the research on the weak magnetic control strategy of the asynchronous motor used in the pure electric vehicle was analyzed,the mathematical model and the vector control strategy of the asynchronous motor in different coordinate systems were demonstrated,the range of the wide speed regulation was classified,and the advantages and disadvantages of traditional and new flux weakening control strategies of asynchronous motor were compared. The results show that the traditional 1/ωrmagnetic flux weakening strategy is applicable to the field of asynchronous motor driving with low performance requirements,and the weak magnetic control strategy for variable expected voltage has better application advantages in electric vehicles.
