摘要/Abstract

摘要： 最大转矩电流比(MTPA)控制可以有效提升同步磁阻电机(SynRM)的效率。虚拟信号注入法是近年来实现MTPA控制的研究热点之一,现有的虚拟单极性方波信号注入法仍存在一定稳态误差,并且存在无效计算时间。提出一种虚拟双极性方波信号注入法,在单极性方波的基础上增加负极性信号,填补了单极性方波的无效计算时间,消除了单极性方波注入法存在的稳态固有误差,实现精准MTPA控制。通过理论仿真和硬件实验,将虚拟双极性方波注入法与现有的虚拟单极性方波注入法进行比对,验证了该方法具有更高的稳态精度,且具有良好的动态性能,能够实现SynRM的高性能MTPA控制。

Abstract: The maximum torque per ampere (MTPA) control can improve the efficiency of the synchronous reluctance motor (SynRM), and the virtual signal injection method (VSIM) is one of the research issues to achieve the MTPA control in recent years.The existing virtual unipolar square wave signal injection method still suffers from errors and invalid computation time.A virtual bipolar square wave signal injection method was proposed.The bipolar square wave added the negative polarity signal to the unipolar square wave, to fill the invalid computation time, and eliminated the inherent steady-state error of the unipolar square wave injection method to achieve accurate MTPA control. Through simulations and experiments, it was verified that the proposed method had high steady-state accuracy and good dynamic performance, and achieved high-performance MTPA control.

Key words: synchronous reluctance motor (SynRM), maximum torque per ampere (MTPA) control, virtual signal injection method (VSIM), bipolar, steady-state accuracy, computing efficiency
