电动车最大效率控制下转子磁通变化的研究

STUDY ON ROTOR FLUX VARIATION UNDER EFFICIENCY OPTIMIZATION CONTROL IN ELECTRICAL VEHICLES

在电动车用感应电动机驱动系统最大效率控制技术基础上，着重分析了转子磁通的变化规律，并与Ｕ／ｆ恒定控制、矢量控制作了比较和分析。

In this paper,variation strategy of rotor flux is researched on the base of efficiency optimization control(EOC)of induction motor drive system in electrical vehicles(EV).Detail analysis of this variation strategy of EOC completed and compared with classical U/f control and vector control.
