CONSTRAINED LEAST-SQUARES METHOD FOR THE ESTIMATION OF THE ELECTRICAL PARAMETERS OF AN INDUCTION MOTOR

This paper presents for the first time the analytical solution of the constrained minimization for the on-line estimation of the electrical parameters of an induction motor. The method is mathematically fully described and its goodness is verified experimentally on a suitably set up test bench. This methodology permits the almost correct computation of all the so called K-parameters, which is not always the case in current literature, thus resulting in the correct estimation of the electrical parameters.
