摘要: 本文利用异步电动机的数学模型推导出电流型转差变频调速系统的传递函数,进而推导 出电流给定△I*1=f(△ω2)的动态变化规律,用此规律在转差变频调速系统中实现了控制.Abstract: In this paper the transfer function of current type slip speed control system with variable frequency is derived from the model of induction motor. Furthermore, dynamic law of current given as △I*=f(△ω2) has been derived and used in slip speed control system with variable frequency.
