Abstract
AbstractIn this paper, our interest is in the identification of a special class of electromechanical systems: a motor‐drive system using the continuous wavelet transform method. This new modal analysis technique is evaluated in terms of its accuracy in the estimation of the modal parameters, its ability in distinguishing and separating several modes, its resistance to noisy conditions, and its usability with different excitations types. For this investigation, two models of elastic drive systems are considered: the two‐mass model and the three‐mass model. Simulation results of the study are presented, and the effectiveness of the developed identification method is discussed. © 2012 Institute of Electrical Engineers of Japan.
