Abstract :
The simultaneous observation of rotor flux and angular speed in induction motor drive is subject to unstability problems, especially in regenerating mode. Many solutions have been proposed in the literature. In this article, an optimal observer design is proposed in order to reduce the unstability region to a simple line in the torque/speed plane
