Identification of asynchronous machine parameters by a recursive least-squares method

Abstract

In this paper, an identification of asynchronous machine parameters by a recursive least-squares method with forgetting factor is presented. The authors perform an identification procedure based on stator voltage and current measurements. The authors use band-pass filters to stabilize the identification algorithm. For different time sampling, they have obtained the parameters of a 1.5 kW/4.4 A/380 V asynchronous machine. The obtained performances show that this procedure can be used for an on-line identification in the indirect vector control of the asynchronous machine.<>
