Abstrncf - This paper presents a new method of rotor time
constant estimation using artificial works, for the 11. ROTORRESISTANCE IDENTIFICATION WITH ARTIFICIAL

controlled induction motor drive. The hack propagation neural
network technique is used for the real time adaptive estimation. The rotor resistance of an induction motor can be estimated
The error between the desired state variable of an induction with the adaptation scheme using the work, as
motor and the actual state variable of a neural model is back illustrated in Fig. 2. Two independent observers are used to
