Concept for Distributed Field Oriented Control of Twelve-Phase Permanent Magnet Machine

Designing an effective control strategy for an open-delta modular multi-phase machine includes challenges such as common mode currents, varying self and mutual inductance, and the coupling between phases. This problem is unique to open delta machines and the focus of most available literature is on neutral point connected machines. This work addresses these challenges by developing a distributed FOC strategy that includes these important parameters.
