摘　　要：无换向器电机是一套复杂的机电一体化装置,为了确定主回路、控制回路的结构和参数设计,需要建立接近于实际系统的仿真模型。结合Matlab仿真软件提供的电力系统工具箱与编程功能,利用双闭环调节器构成调速系统,并用有限状态机方法设计控制软件算法,建立了无换向器电机的全程时域仿真模型。利用该模型分析了无换向器电机的起动过程、调速性能以及平波电抗器选型。仿真与实际波形分析验证了仿真模型的正确性。Commutatorless motor is a complex mechano-electronics device. In order to confirm the structure of main circuit and control circuit and design parameters of components, it is necessary to set up the simulation model approaches of the practical system. Combining power system toolbox and programming function which are provided by Matlab, and using double closed-loop regulator to form the speed adjusting system, and adopting finite state machine method to design control software algorithm, whole process time-domain simulation model of commutatorless motor is set up. With this model, starting process of the motor, ASD performance of the motor and the parameters of smoothing reactor are analyzed. Waveforms of the simulation and the experiment are analyzed to verify correctness of the simulation model.
