摘　　要：为了能够准确、灵活地描述无刷直流电动机控制系统,经过理论推导,建立了电机本体和驱动电路的动态数学模型,为研究该系统在MATLAB环境下的创建过程做好理论准备。借助Simulink的S函数对实例电机及其驱动电路进行了仿真模块的创建,将两者有效结合在一起。最后通过系统仿真,给出了不同电量的仿真波形,进而验证了所建模型的有效性。To describe the control system of brushless DC motor（ BLDCM） accurately and flexibly,after theoretical deduction,the dynamic mathematical model of the motor and the drive circuit were established for theoretical preparation to research the system created under the MATLAB environment. The example of motor and drive circuit were combined together by the S- function in the Simulink. The system simulation shows the waveforms of different electrical variables,and verifys the validity of the model.
