Abstract

A model predictive control scheme for multiphase in- duction machines, configured as multi-three-phase structures, is proposed in this paper. The predictive algorithm uses a direct flux vector control scheme based on a multi-three-phase approach, where each three-phase winding set is independently controlled. In this way, the fault-tolerant behavior of the drive system is im- proved. The proposed solution has been tested with a multimod- ular power converter feeding a six-phase asymmetrical induction machine (10 kW, 6000 r/min). Complete details about the predic- tive control scheme and adopted flux observer are included. The experimental validation in both generation and motoring modes is reported, including open-winding postfault operations. The ex- perimental results demonstrate full drive controllability, including deep flux-weakening operation.
