Public ISBD [article]  inIEEE transactions on industrial electronics > Vol. 56 N°1 (Janvier 2009) . - pp. 202 - 211 Titre : Novel modeling and damping technique for hybrid stepper motor Type de document : texte imprimé Auteurs : Tsui, K.W.-H., Auteur ; Cheung, N. C., Auteur ; Yuen, K.C.-W., Auteur Année de publication : 2009 Article en page(s) : pp. 202 - 211 Note générale : electronics Langues : Anglais (eng) Mots-clés : digital control  machine open loop systems  stepping motors Résumé : It is well known that commercial hybrid stepper system has one or more low-speed resonant points. However, this characteristic cannot be accurately modeled without high-order equations or complicated measurement of motor parameters. In this paper, a novel approach is proposed to model the behavior of a commercial 1.8deg hybrid stepper motor accurately and efficiently. Also, model-based damping algorithms for both open-loop control and servo control are proposed. Simulation and experimental results show that the proposed algorithms can effectively eliminate low-speed resonance and vibration of the stepper system. The algorithms are efficient enough to be implemented on commercial DSP-based controllers without sacrificing motion control performance.
