Abstract :
This paper presents a new method for online torque estimation of an induction motor. It uses a fuzzy logic based system with five inputs: the measured stator winding temperature; the measured stationary d and q components of the stator current; and the estimated stationary d and q components of the rotor flux. The estimator has been trained using a simulator of an induction motor and then, implemented on a digital signal processor. Experimental results obtained with a rotor-flux-oriented vector-controlled 10 hp drive show good agreement between estimated and real torque
