摘要
从电动车电驱动系统的基本特性出发 ,建立了电动车工况下最大效率控制的感应电机驱动系统仿真模型 ,通过实例在考虑饱和非线性的条件下进行了最大效率控制的仿真计算。针对感应电动机损耗将最大效率控制与传统U/f恒定控制进行了比较分析 ,对最大效率控制产生的损耗变化及分布规律进行了研究 ,对铁心损耗的影响进行了分析。
According to the essential trait of electric drive systems in electric vehicles (EVs),it is built that the simulation model of induction motor drive system of EVs in efficiency optimization control (EOC),which suits different motors for simulation and research concerning the running condition of EVs.Taking nonlinear saturation problem into consideration,simulation study on EOC is proceeded by using an actual motor acting as an example,comparison of EOC with classical U/f control mode is completed at the same time.It is analysed that the variation of losses and their distribution causing by EOC.Effect of iron losses is researched in detail.
