摘要
首先基于直接转矩控制原理提出了双定子/双转子永磁同步电机双转子运行时,内部电机控制电压矢量的确定方法,然后考虑到内部电机特点与Matlab所提供永磁电机模型的差别,建立了电机等效仿真模型。仿真结果证明本文所提出的方法有效。其结果对在混合动力电动汽车中开发双定子/双转子永磁同步电机的直接转矩控制系统具有意义。
First, a method of determining the voltage vector of inner machine when PM synchronous double-rotor or double-stator operates is presented on the basis of the principle of direct torque control. Then the equivalent simulation model is established with consideration of the difference between characteristic of inner machine and model of PM machine provided by Matlab. The simulation results show that the method is effective, and those results are of significance to develop the direct torque control system for PM synchronous double-rotor/double-stator machine in hybrid electric vehicles.
