In this paper, a single-phase open-circuit fault-tolerant control method for three-phase permanent magnet synchronous motor (PMSM) is proposed. Based on the 4-leg inverter and the redesigned vector transformation method, the switching of the motor control strategy after a single-phase open circuit can be realized, and the control characteristics of the motor are unchanged. This fault-tolerant control method can be easily combined with other control strategies and has a wide range of applications.

The benefits of a five-phase permanent magnet synchronous motor (five-phase-PMSM) are its compact size, high fault tolerance, low voltage, and high output. The drives of this kind of machines can be enhanced using model predictive torque control (MP-DTC) technique. The outcomes of this technique with additional weighting factors are reduces the complexity of calculation, and reduction in current harmonics, which present in harmonic subspace in standard model predictive torque control. Decrease the low-order harmonic constituents of stator currents and alleviation torque ripple can be achieved by optimizing the objective function. Adding current limitations and switching frequency-weighting factor improves the cost function. The suggested technique can provide superior steady-state performance and keep the quick transient performing as a possible characteristic of the MP-DTC scheme. Thus, with the advantageous steady state and dynamic performing obtained concurrently, the most important aspects of the suggested system are the reduced mathematical burden, and with simplified objective functions compared to classic MP-DTC structure. The proposed method reduced the torque ripple from (3.49%) in a traditional method to (0.58%).

“…In [13] the authors employed a fourth leg in a manner that it replaces the faulty leg, yet the same drawback of extra complexity and additional cost and size remains the same. In [14] fault-tolerant systems of five-phase permanent magnet motor drive was studied. However, the multiphase machines are not a suitable solution in some application owing to the extra weight and costs.…”

This paper presents an integrated solution for a fault-tolerant three-phase permanent magnet synchronous motor (PMSM) field-oriented control drive subjected to an openphase 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.
