本篇主題為針對感應馬達速度控制所做的模擬。首先推導感應馬達的數學模型，接著說明如何用兩軸旋轉座標系與磁場導向做到方程式的化簡與解偶以便於控制上的要求，接著提出兩個命令控制變數：同步旋轉座標系下的d軸轉子磁通與q軸定子電流做為控制器的輸入，最後從模擬的實驗數據上驗證此方法的可行性，的確能達到準確的速度命令追蹤。 The simulation of the speed control of an induction motor is presented in this study.First, the mathematical model of an induction motor is derived and then how to use coordinate transform is proved and rotor flux field-oriented stragy issued to simplify the math model to achieve control conveniently. Next, two control variables:d-axis rotor flux and q-axis stator current both in the synchronous rotating frame are adopted into the controller to achieve speed command tracking.Simulation results show that this controll scheme is feasible because the speed response is accurate and steady.
