Space-Vector Dynamic Model of Dual-Three Phase PMSMs and related Identification Technique

Abstract

This paper presents a dynamic model of the dual three-phase PMSM in the sD-sQ, z1-z2 and o1-o2 subspaces based on the vector decomposition concept. The model has been described in state form and has been presented in stationary and synchronous reference frames. Furthermore, a suitable identification methodology has been conceived permitting the estimation of the model parameters and the full characterization of the machine from the magnetic point of view. The proposed identification technique has been implemented experimentally on a suitably devised test set-up.
