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△I1*=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.
In this paper, the mathematical model of induction motor is used to deduce the transfer function of the current-type slip frequency conversion speed control system, and then the dynamic change law of current given ΔI1 * = f (Δω2) is derived. With this rule, System to achieve the control.
