摘要
从无刷直流电机(BLDCM)的工作原理和结构出发,在分析BLDCM数学模型的基础上,采用模块化方法,在Matlab/Simulink中建立BLDCM转速、电流双闭环控制系统模型。利用该模型进行电机动静态性能的仿真研究,仿真结果与理论分析一致,表明该方法建立的BLDCM控制系统仿真模型合理、有效。该模型简单、直观、参数易于修改和替换,可方便的用于其他控制算法仿真研究。
Based on the principle and structure of the brushless DC motor（BLDCM）,and analyzing the mathematic mode,a simulation model of BLDCM speed and current double loop control system is established in Matlab/Simulink by the modular design.The static and dynamic performances of BLDCM were simulated,and the reasonability and validity were testified by the coincidence of the simulation results and theory analysis.This model has the virtues of simpleness,understandability,modifying parameters easily,also suitable for verifying the reasonability of other control algorithms.
