PARAMETER ESTIMATION FOR A,C, MACHINES

This paper present a method for estimation of synchronous machine parameters. The authors have applied the reference model method to a linear model of a converter-fed synchronous machine motor drive. Using input-output data from different transient condition, machine parameters have been estimated. The Levenberg-Marquardt method is used for minimising the cost function based on the least squares criterion. The existence of good concordance between the process and model outputs confirms the validity of the estimation method.
