摘要
在建立了永磁同步电机数学模型的基础之上,仿真模型中包含了建立三相电流源型逆变器模块、DQ向ABC转换模块等,并改进了电流滞环控制模块。文中提出了一种分析永磁同步电机(PMSM)的新方法,分析了伺服系统在不同给定速度下的表现稳定性以及转矩电流的变化等。
On the basis of mathematical model of permanent magnet synchronous motor(PMSM),the simulation model that consists of three-phrase current inverter block,DQ-to-ABC transition block,etc.,improves hysteresis current control block.This passage proposes a novel method of researching PMSM,and analyses the performance and the variety of stator current of PMSM on different situations of given speed.
