Abstract :
This paper presents a new rotor flux and rotor speed observer of induction motor. The new observer is based on an adaptive mechanism. The design of the new observer is done using the notion of Lyapunov stability. The observer is designed to be used within a speed sensorless direct rotor field oriented control of induction motors.
