“…The structural diagram of the 6*3-phase PM energy storage motor system with PPC strategy is shown in Figure 8. According to Figure 8, the operating principle of the 6*3-phase PM energy storage motor drive system is as follows: According to (10) and (12), the predicted values of stator flux and torque at the (k + 1)T s moment can be calculated. Then, the switching signal of the VSI can be obtained by substituting the predicted values and the response values into the cost function (8).…”

“…In [11], a novel multi-phase PM motor design with a dual three-phase asymmetric stator winding was proposed, which can achieve the higher torque density levels and excellent torque quality. In [12], a novel six-phase PM motor with a new asymmetric stator ac winding scheme and placement was proposed, which can obtain a better motor performance than conventional dual three-phase PM motors. To improve the fault tolerance of motor drive system, a dual three-phase 12-slot 10-pole PM motor was designed in [13], which can avoid excessive torque ripple and unbalanced radial forces in faulty operating conditions.…”

High power density energy storage permanent magnet (PM) motor is an important energy storage module in flywheel energy storage system for urban rail transit. To expand the application of the PM motor in the field of urban rail transit, a predictive power control (PPC) strategy for the N*3-phase PM energy storage motor is proposed in this paper. Firstly, the output characteristics of the N*3-phase PM energy storage motor are analyzed by using the finite element method, and the mathematical model of the N*3-phase PM energy storage motor is established. Then, the topological structure and operation principle of N*3-phase PM energy storage motor system is illustrated. Furthermore, the N*3-phase PM energy storage motor system driven by six parallel voltage source inverters (VSIs) is proposed to generate the required power. Finally, a novel predictive direct power control method is developed for the N*3-phase PM energy storage motor. The feasibility and effectively of the proposed PPC method are verified by experiment and simulation. Comprehensive simulation and experimental results both show that the proposed PPC method can obtain the lower torque/stator flux ripple, smaller values of THD of stator winding currents, and zero error tracking of stator winding flux.

Single- and Two-Phase Open-Circuit Fault Tolerant Control for Dual Three-Phase PM Motor Without Phase Shifting

A fault tolerant control strategy for dual three-phase permanent magnet synchronous motor (DTP-PMSM) with 0° phase shifting between two windings is proposed in this paper. When a DTP-PMSM suffers from single-or two-phase open-circuit fault, to maintain the torque performance, current in faulty phase must be compensated by other healthy phases, which causes asymmetric self-and mutual inductances. Therefore, the 2 nd harmonic component can be observed in the dq-axis currents and torque ripple also increases. To analyse this harmonic component in two types of faults, post-fault model of no-phase-shifting DTP-PMSM based on vector space decomposition (VSD) method is built in this paper. Then, proportionintegral-resonant (PIR) controller which can be used to suppress the specific periodic disturbance is applied to compensate the 2 nd harmonic components. As the resonant controller is rarely dependent on motor parameters, phase and amplitude of current harmonic, the PIR controller can be applied in no-phase-shifting DTP-PMSM to suppress the harmonic caused by single-and two-phase open-circuit faults. The experimental results validate the effectiveness of the proposed fault tolerant control under single-and two-phase opencircuit faulty conditions. INDEX TERMS Dual three-phase, fault tolerant control, harmonic suppression, vector control.

“…To facilitate the implementation of the control algorithm of the multi-three-phase PMSM, the modular three-phase PMSM with a novel and untraditional stator winding arrangement has attracted the attention of scholars [12][13][14][15][16][17][18][19][20][21]. The merit of the stator winding placement is that the mutual couplings among the multi-three-phase winding sets are negligible.…”

In this study, a novel modular three-phase permanent magnet synchronous motor (PMSM) is proposed for low-voltage high power applications. The proposed modular three-phase PMSM has an independent segregated three-phase winding configuration, facilitating the implementation of the control algorithm. Firstly, on the basis of the electromagnetic properties, the mathematical model of the modular three-phase PMSM is established, considering the asymmetrical mutual inductances investigated by finite element analysis (FEA). Then, the predictive torque control (PTC) method combining the inductance characteristics of modular three-phase PMSM is developed, and excellent performance is obtained by adjusting the stator flux and torque. Finally, simulation and experiment are performed, and the results show that the proposed novel modular three-phase PMSM with the PTC method exhibits excellent control performance, and small stator current total harmonic distortion (THD).
