Online Adaptive Set of Virtual Voltage Vectors for Stator Current Regulation of a Six-Phase Induction Machine Using Finite State Model Predictive Controllers
Description
Virtual voltage vectors (VVV) have been used for the control of multi-phase induction
machines, where different sub-spaces appear related to the torque production and losses generation.
In the literature, several sets of VVV have been used, aiming at reducing harmonic content while
maintaining a low computational burden. This paper proposes the use of different sets of VVV
to regulate the stator current of multi-phase drives using finite-state model predictive controllers.
In the proposal, only one set is active at each control period. This active set is obtained through a
preliminary analysis using performance maps. As a result, a method is derived for the online selection
using the current operating point. The selection is based on a simple computation from variables
usually measured on variable-speed drives. Results are provided for a symmetrical six-phase IM,
showing that the proposal improves the closed-loop performance of the multi-phase drive with a low
computational cost.
