摘要
系统地建立了电动机车驱动用永磁同步电机的数学模型,并在此基础上深入分析了永磁同步电机直接转矩控制(Direct Torque Control,简称DTC)思想。在应用仿真软件构造永磁同步电机、逆变器、电压空间矢量等单元模块的基础上,对理想的永磁同步电机DTC系统进行了仿真及实验研究,比较了不同给定转速时系统的响应,结果符合永磁同步电机的运行特性,证明了永磁同步电机中应用DTC的可行性,也为实际伺服系统的设计和调试提供了新思路。
This article sets up the mathematics model of the permanent magnet synchronous motor(PMSM) systematically used by EV drive,analysis the direct torect control(DTC) principle of PMSM.The DTC of PMSM is establishde based on the ideal model of PMSM and the inverter and the module of voltage space vector.The emulation result indicates the feasibility that DTC applies to PMSM,and the simple control structure and good dynamic respond characteristic of this kind of method.It gives a new way to design serve system.
