| Abstract |
Real-time identification of the rotor parameters with simultaneous speed estimation in induction motor drive is
presented in the paper. The synthesis procedure of the identifier of the rotor parameters, based on the MRAC System Theory, allows to point out the estimation of rotor speed too. An appropriate choice of the reference model allows to find the updating law of the rotor parameters basis on the hyperstability approach. At the same time the adjustable model gives
the rotor speed estimation which converges to its actual value as the rotor parameter error vector converges toward the origin. The parameters convergence is assured thanks to the Persistent Exciting propriety of the input vector. Computer simulations and a DSP-based system (TMS320C30), having 30MHz clock frequency, are used for testing the proposed identifier-estimator in a CRPWM inverter supplied drive. |
