摘　　要：调速系统是电动机降低能耗、改变输出效率的最有效手段之一,尤其是串级调速系统技术的研究长期以来都是科研工作者关注的热点。利用Matlab软件对双馈电机的斩波式串级调速系统设计成转速、电流双闭环控制模式。为了实现调速的控制效果达到最佳,利用斩波器的有效占空比例控制电机转子回路中的附加电势。在一定程度上,为后续进行高效无刷双馈电动机的设计提供具有实际应用价值的参考思路。The speed control system is one of the most effective means for reducing the energy consumption and changing the output efficiency of the motor.Especially the research on the technology of the cascade speed control system has long been a hot spot for researchers.In this paper,the chopper cascade speed regulation system of doubly-fed electric machine is designed into double-closed control mode of speed and current by using Matlab software.The additional potential of the rotor circuit of the motor is changed by controlling the duty cycle of the chopper to achieve the purpose of speed regulation.
