Identification of Induction Machine parameters including Core Loss Resistance using Recursive Least Mean Square Algorithm

Abstract

Determination of electrical parameters of Induction machine (IM) is very important especially in field oriented control. The identification schemes proposed in the literature estimate only four of the five electrical parameters of IM, when core loss resistance is neglected. This paper proposes a novel parameter identification method that estimates all the six electrical parameters of IM considering the impact of core loss resistance also. Recursive Least Mean Square (LMS) algorithm is used to identify the machine parameters in the proposed method. The proposed identification scheme is validated through simulation results.
