Resumen:
This paper proposes a Field Oriented Control (FOC) for a Permanent Magnet Synchronous Machine (PMSM) which is supplied by a Parallel Multi-Inverter System. The parallelization of the Voltage Source Inverters is safely achieved using a V-f Droop Control strategy as a distributed generation system would be considered like in Smart-Grids. This novel technique is the combination of the previous mentioned both strategies, and will be key when answering to the need of modularity, scalability, redundancy and parallelization for electrical machine control systems. Theoretical and experimental analysis are provided in order to validate the new combined control strategy which fulfills the motor control requirements while current balancing is safely achieved between individual parallelized inverters.
