摘要
从电动车用感应电机的基本特性出发 ,建立了考虑铁耗的感应电机转子磁场定向模型 .在分析电机损耗的基础上 ,提出了一种混合搜索技术 ,即通过电机损耗模型离线计算励磁电流设定值的下限 ,采用黄金分割法在已经缩小的范围内进行搜索 .为了保证系统的动态响应 ,给出了模式切换的准则 .通过实验和仿真 。
According to the basic character of induction motor used in vehicle, this paper proposes a field oriented control model considering the iron losses. After analysing the losses model, a hybrid search technique is given. The minimum flux current is calculated according to losses model, then golden search technique is used in limited scope. What is more, switch method is provided to get quick respond. Finally, simulation and experiment have been tested to validate the theoretical development.
