摘要
本文根据SR电机状态方程及基尔霍夫电压电流定律推导出6/4极SR电机主电路数学模型,利用小信号拢动法给出SR电机电压斩波控制方式下的传递函数,并结合微机PID控制技术给出SRD系统的传递函数,分析系统运行的稳定性,最后给出一个小功率SRD系统控制实例。
This paper,we derived the main circuit mathmatical model of 6-4 pole SR motor from SR motor state equations and kirchhoff's laws.By means of the small signal disturbance,it also reached the transfer function of SR motor under voltage chopped wave control and obtained the transfer function of SRD system by integrating microcomputer PID control technique.And the stabitity of the system is analyzed. In the end,It give a control example of the small power SRD system.
