磁場導向控制感應電動機控制器參數之自我調適

　　　　　近年來，感應電動機已被廣泛地使用在許多工業應用的領域中，更由於磁場導向 控制技術的成熟，使得感應電動機的高精度控制得以實現。 本論文是以向量控制原理為基礎，藉由感動電動機轉矩方程式得到一個簡化的電動機控制模 型，我們提出二種調適感應電動機速度控制器參數的方法： 一為運用Ziegler-Nichols法則離線調適感應電動機速度控制器參數， 一為結合極點配置法與最小平方遞迴估測法做電動機速度控制器參數線上自調。 最後，本文以一個PC-based的實驗系統來驗證，實測結果說明不論是額定轉速或低轉速命 令下，均有相當不錯的響應。
　　　　　Recently, induction motors have been widely used in many fields of industrial applications. Moreover, due to the development of field-oriented control technique, the control of a high performance induction motor becomes realizable. Based on the vector control theorem we propose two methods to tune the parameters of the speed controllers of induction motors with the use of a simplified model from the torupe equation. One is to tune the parameters off-line by using Ziegler-Nichols method. Another is to tune the parameters on-line with the combination of pole placement and recursive least square estimation method. Finally, we use a PC-based experimetnal system to verify the feasibility of the proposed method. Experimental results indicate that there are quite satisfactory responses at both the rated speed and low speed.
