摘 要: 建立了双转子永磁同步电机的仿真模型,介绍了模型中各个仿真模块在MATLAB/Simulink中的建模方法。使用矢量控制系统和空间矢量控制系统对所建立的电机模型进行了仿真,测试了模型的正确性。比较了矢量控制和空间矢量PWM控制的转矩、转速和电流响应曲线,并且深入分析了双转子永磁同步电机稳定运行和瞬态运行时的特点,结果表明选用不同的控制策略时,动、静态响应有所区别,适用于不同场合,为双转子电机的实践应用提供了技术参考。 This paper investigates modeling and simulation of dual-rotor permanent magnet synchronous motor. The emulated model of a novel DRPMSM is constructed and constitution of every modules of the model based on MATLAB/Simulink is introduced in de tail in this paper. In order to test the correctness of the emulated motor model, vector control (VC) system and space vector PWM control (SVPWM) system are used to emulate the model of the motor. The testing results show the correctness of the emulated motor. This paper compares the torque, rotation speed and current trail route of VC and SVPWM strategies. The results show that u sing different control strategies can get different systems'dynamic and static responses satisfy the needs of different conditions. At the same time, it analyzes the characteristics of dual-rotor permanent magnet synchronous motor in steady operation and transient run time.
