Fully decentralized control strategy for synchronous open-winding motors

Résumé

This paper proposes a decentralized control strategy for multiphase open-winding permanent magnet synchronous motors (OW-PMSMs). The main goal is to achieve high levels of fault tolerance on the control part. Indeed, multiphase motors are well known for their fault tolerance and reliability, but a centralized control loses this advantage in case of control system fault. This work tries to reduce dependencies between each winding of an OW-PMSM by proposing a decentralized control strategy where each motor winding has its own control system. To obtain desired torque, each winding current must track a sinusoidal current reference. A flatness-based control is used to improve the tracking dynamics. Simulations on a three-phase OW-PMSM are performed in health and fault conditions. Results validate the proposed decentralized control strategy and show a high availability of the controlled OW-PMSM drive.
