摘要
针对常见有刷直流电动机的一些缺陷,提出了基于DSP来实现永磁无刷直流电动机速度控制的一种方案。介绍了当前无刷直流电动机控制的发展趋势和常见的新型控制方法,最后采用端电压过零检测法和预定位起动方法,实现了基于TM S320LF 2407的无位置传感器永磁无刷直流电机的速度控制。
Aiming at the disadvantage of generally DC motor with brush,this paper presents the control of Brushless Permanent Magnet DC motor using the DSP,introduces the future of the control of BLDCM and some new methods in controlling DC motor. In the end,a complete solution proposal is presented in the paper. It deals with sensorless algorithms as an alternative to position sensors for speed control in Brushless Permanent Magnet DC motors based on TMS320LF2407,using the back-EMF commutation method and the start method by means of rotor pre-setting,
