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函,进而推导出电流给定△I~*_1=f(△ω_2)的动态变化规律,并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 asynchronous motor is used to deduce the transfer function of current-type slip frequency conversion speed control system, and then the dynamic change law of current given ΔI ~ * _1 = f (Δω_2) is deduced. Frequency control system to achieve the control.
