Description

The purpose of this study is to establish the stable operation of the sensorless induction motor drives with stator resistance adaptation using estimation error index. The stator resistance estimation is difficult at no load and zero frequency. These problems are solved by decoupling adaptive schemes and adjusting the adaptive gain. The stability analysis by pole placement and the experimental results show the effectiveness of the method.
