| 摘 要： | 基于直接转矩控制的方法,研究了电动汽车用永磁同步电机(PMSM)直接转矩控制(DTC)系统中电压空间矢量选择原则。提出了控制系统中引入零电压矢量的方法,同时针对磁链处于边界区引起的起动困难的问题对开关表进行了修正。开发了基于数字信号处理器(DSP)的电动汽车用PMSM的DTC系统,并进行了低速下的试验研究,取得了较好的控制效果。

| Abstract: | Study on the selecting principle of space voltage vector based on PMSM direct torque control(DTC)and a method which use zero voltage vector in steady state are introduced.Furthermore,modifying the switch table to prevent the startup difficult when the flux is at the range of the sector is presented.A DTC drive system for EV based on DSP is developed.The experimental result of the DTC system at low speed was presented and proves that the control system can meet the requirement of a drive of EV. |
