永磁无刷直流电机在MATLAB中的仿真研究

摘要

This paper introduced the working principle of permanent magnet brushless DC motor, and its mathematical model was deduced, and then the simulation model of the speed control system of the PI control was established based on MATLAB/Simulink. Finally, the simulation results were analyzed, and the simulation results showed that the motor has better dynamic and static characteristics under the no-load and load conditions.%介绍了永磁无刷直流电机的工作原理，建立了其数学模型，然后在MATLAB/Simulink中建立了其转速单闭环PI 控制的调速系统的仿真模型，最后对其仿真结果进行了分析。仿真结果表明，电机在空载和带载情况下，具有较好的动静态特性。
