无刷直流电动机系统的电流相位闭环控制

Current Phase Close-loop of Brushless DC Motor (BLDCM) System

分析了实现无刷电流电动机磁场定向运行的最佳超前角，提出了一种带有相位闭环控制的无刷直流电动机系统，完成了超前角的自动调节，实现了系统的磁场定向运行。本文给出了该系统的完整描述，并进行了实验验证。

After the analysis of the optimal leading angle for filed-oriented control of BLDCM system,this paper puts forward a new BLDCM system with current phase feedback,the leading angle is auto-tuned in the system,and filed-oriented control of BLDCM system is realized.The whole system is described in detail in this paper,and experiments have been made to verify the method
