Advantages of Communication in Double Three-Phase Surface Permanent Magnet Machines Fed by Independent Inverters

This paper deals with a double three-phase Surface Permanent Magnet (SPM) drive where two independent three-phase inverters are supplying the same electrical machine. This work highlights how the magnetic coupling of the two windings affects the control performance. A new control strategy based on a low bandwidth communication, aiming to improve the performance of the system, is presented and validated by numerical simulations.
