This paper presents an integrated solution for a fault-tolerant three-phase permanent magnet synchronous motor (PMSM) field-oriented control drive subjected to an open-phase fault (OPF) integrated with effective fault-tolerant detection methodology. The fault detection methodology is based on model predictive current control (MPCC), which is easy to apply, detect OPF in a range of microseconds, and robust under-speed or load transient. On the other hand, the fault-tolerant compensation is based on a neutral point connection together with stator current regulation to maintain the magneto-motive force (MMF) unchanged under open-phase failure. Controlling the motor phase currents in the post-fault condition ensures a rotating magnetic field similar to that produced during healthy conditions thus, reducing the saturation impact and ensuring the reliability of the control operation. The proposed integrated fault-tolerant drive is validated using MATLAB simulation that ensure the effectiveness of the proposed solution in steady state and during transients under different loading and rotor speed condition.
