基于双三相线性霍尔传感器的嵌入式磁编码器在永磁同步电机中的实现

Normally, three-phase linear Hall sensor-based embedded magnetic encoder (EME) are used in permanent magnet synchronous motors to detect the rotor angle, in which prefilters are used to suppress the harmonic disturbance. However, due to the employment of prefilters, this EME system shows large estimated angle error at low-speed regions and weak dynamic response performance. In this letter, a dual ...
