本文提出一適應控制法則以改善感應馬達時變參數的影響。首先，利用函數逼近法來設計迴授線性化適應控制器以改善未知時變參數對感應馬達之影響。同樣的，利用函數逼近法來設計參考模型適應控制器。再者，本文將對未知解耦矩陣提出一種新設計，以解決其反矩陣singular的問題，並將新設計應用於以上兩種方法以電腦模擬驗證此設計之可行性。由電腦模擬的結果顯示，此新設計對於感應馬達的控制具有優良的特性。

The purpose of this paper is to propose an adaptive controller for induction motor control system. Some of the system parameters are assumed to be unknown time varying without any information of their variation bounds. Traditional adaptive control algorithms are not application to this kind of systems due to their time-varying nature. Here, a function approximation based controller is designed to transform the time-varying parameters into a linear combination of known orthonormal basis. Besides, the singularity problem of the decoupling matrix is dealt with by redesigning the parameter update algorithms. Simulation cases shown that the proposed schemes have excellent performance.
