摘要
本文在分析无刷直流电机系统数学模型的基础上,提出了无刷直流电机控制系统仿真建模的新方法。在Matlab/Simulink中,通过S-函数独特的结构,建立独立的功能模块,如电动机本体模块、反电动势产生模块、速度PI控制模块、电流PI控制模块等,再进行功能模块的有机整合,搭建无刷直流电机控制系统快速高效的仿真模型。该方法成功地应用于电动车驱动系统的设计仿真。
Based on the mathematical model of the Brushless DC motor （BLDCM）, a novel method for modeling and simulation of BLDCM has been proposed. In Matlab/Simulink, S-function is categorized into three special structures ,then the isolated functional blocks, such as motor block, speed PI controller block, current PI controller block, EMF generated block etc have been modeled By the organic combination of these blocks, the model of BLDCM control system can be established efficiently. This novel method is suc- ceed in designing and modeling actual BLDCM Drives for Electrical bicycle.
