Finite Control Set MPC for Open-Phase Fault Tolerant Control of Synchronous Reluctance Motor

In this paper, a model predictive control (MPC) of a synchronous reluctance motor (SynRM) with a fault tolerance against an open-phase fault is proposed. The MPC algorithm is based on the finite control set strategy and takes into account the modified inverter topology which was used to make the fault tolerance possible. The algorithm is intuitive and easy to implement. It provides a fast torque response and smooth transition into fault operation without any torque drop.
