Resonance identification for magnetic-geared motors using improved second-order generalized integral frequency-locked loop
Abstract
This article aims to improve the simplicity, speed, and accuracy of the resonance frequency identification algorithm. First, a brief introduction to the resonance of magnetic-geared motors (MGM) is provided. Then, a simple and more easily implementable identification method combining the second order generalized integrator and frequency locked loop (SOGI-FLL) is introduced. Based on this, to reduce convergence time and increase control degrees of freedom, an improved second order generalized integrator-frequency locked loop (ISOGI-FLL) identification algorithm is proposed, and its performance is analyzed. Finally, the effectiveness of the proposed algorithm is validated through experiments.
