Globally Stable Adaptive Observer for Systems of General-Purpose Industrial Asynchronous Electric Drives

摘要

A structure and methods for the parametric synthesis of an adaptive observer that is formally stable in the entire plane of mechanical characteristics of the electric drive and enables one to identify the electric rotation frequency of the rotor, the support vector of flux linkage, and the active stator resistance are described. Results of modeling a general-purpose industrial electric drive with the developed identification algorithm are presented.
