摘要/Abstract

摘要：

对永磁同步电机无位置传感器控制技术的研究十分有意义。由于注入高频信号必然增加对应的损耗,因而在现有双极性方波注入的基础上,提出了单极性方波注入法,并用JMAG-Simulink联合仿真验证方法,证明在保证估算转子位置精度的前提下,可以有效降低相关的损耗。在以TMS320F2812DSP控制芯片为核心的实验平台上进行了实验验证,验证了单极性方波注入控制的有效性。

Abstract:

The study of sensorless control of permanent magnet synchronous motor (PMSM) is very meaningful. As the high-frequency injection signal will inevitably increase the corresponding loss, a new wave called unipolar square wave injection sensorless control algorithm was protected based on bipolar square wave injection. The JMAG-Simulink joint simulation results show that the loss caused by the injection signal can be effectively reduced injecting the unipolar square wave without sacrificing accuracy of rotor position angle observed by PLL. The experimental verification using unipolar square wave injection sensorless control algorithm was carried out on the platform with TMS320f2812DSP as the core.

Key words: permanent magnet synchronous motor (PMSM), sensorless control, unipolar square wave, lower loss, joint simulation
