Parameter Identification of an Induction Machine for Diagnosis

Abstract

this paper presents an identification method achieving estimation of induction machine electrical parameters. Originality of this work holds in the machine model used. It is a non-linear continuous time model defined in the (abc) frame, whose parameters are not dependent on rotor position. This model is well fitted for non-linear parameter identification algorithm, in order to apply a fault diagnosis method. A recursive algorithm has been derived from the off-line one, allowing to track parameter variation. Some experimental results conclude this paper
