Research on Adaptive Rotor Flux Observer with the Speed Feedback and Rotor Resistance Disturbing

Abstract:

Article Preview

Rotor flux observation is a key step in implementation of a field-oriented vector control system. Aiming at eliminating the influence of the actual speed fluctuation and rotor resistance variety, an adaptive rotor flux observer was proposed to accurately estimate the flux of induction motors in modern high performance drivers, based on the conception of close-loop flux estimation and the extended state observer theory. The performance of the proposed scheme is verified through simulation and experiment.
