Abstract :
This paper proposes an exact (Kalman-like) observer for the simultaneous state and parameter estimation in asynchronous motors — including speed and resistant torque estimation —, as well as a simulation study of its use under an estimate-based speed control scheme. The simulation setup includes the model of a PWM-controlled voltage source inverter, and the results are quite promising.
