基于高频方波电压注入法的无传感器IPMSM研究

摘要

The basic mathematical model of the IPMSM was analyzed,a new sensorless control technology (high-frequency square-wave voltage injection method) was put forward and the detailed theoretical derivation was conducted.Without any filter used,this method almost had no phase delay.The simulation platform based on MATLAB/Simulink was built and the simulation analysis was carried out.The experimental platform based on TMS320F2812DSP control chip was built and the experimental verification was also conducted.The simulation and experimental result proved this method to be true and the expected goal was achieved.%分析了IPMSM的基本数学模型,提出了新的无位置传感器控制技术——高频方波电压注入法,并对它进行了详细的理论推导.该方法不需要任何滤波器,基本不存在相位延迟.基于MATLAB/Simulink搭建了仿真平台,并进行了仿真分析.以TMS320F2812DSP控制芯片为核心搭建了实验平台,并进行了实验验证.仿真和实验结果证明了该方法的正确性,达到了预期的目标.
