基于MATLAB的永磁同步电机变频调速系统的仿真及研究

摘要

Frequency control technology is one of the research focuses of permanent magnet synchronous motor.Based on the frequency control theory of permanent magnet synchronous motor,the frequency control of the starting,braking and simulation model of three-phase synchronous motor were built by MATLAB.The change of the armature current,power Angle and speed of single-phase were studied by dynamic simulation.The research method and technical reference of frequency control of permanent magnet synchronous motor were provided in this study.%变频调速技术是同步电机的研究热点之一；基于永磁同步电机变频调速理论，采用MATLAB建立了三相同步电动机启动、制动和变频调速的仿真模型；通过动态仿真研究了这三种过程中单相的电磁功率、电枢电流、功率角及转速的变化规律，为同步电机变频调速的研究提供了研究方法和技术参考。
