Recursive Prony's Method for Improving the Monitoring of Electrical Machines

Abstract

Prony's method has been proposed in order to improve the monitoring of electrical machines. The paper shows that the method is efficient to track frequency deviations. The proposed method is advantageous over the method proposed in (Costa et al., 2004) because the former does not rely on the previous knowledge of fundamental frequency. It has also been showed that the quantization can deeply affect the spectrum of the analyzed signals
