永磁无刷直流电机PI调速器的研究

The research of brushless electrical machine PI regulator

本文介绍了无刷直流电机PI调节器。速度调节器的输入量为转速与反馈的偏差值,输出为电流环电流。电流与反馈的偏差值为电流调节器的输入,调节器的输出决定开关管的占空比。由软件完成转速、电流双闭环PI调节以及位置、转速信号的处理。系统具有调速系统调试方便、精度高等特点。

This article describes the brushless electrical machine PI regulator.Speed controller input is the values for the deviations of speed and feedback,the output is current loop current.The current regulator input is the values for the deviations of current and feedback,the output of the regulator decided to switch tube.The software also resolves the processing of speed and position.The speed control system has debug easy,and precise.
