“…The dual three-phase machine drive (dual-PMSMs) as a popular multiphase machine drive, is received benefits from the collaboration of two groups of three-phase windings to vanish the torque harmonic pulsation. Meanwhile, the advanced control technology and reliability issue are the essential property of driving systems in various industrial and military applications [3]. At present, most research on dual-PMSM drive systems used in practical applications, that employs proportional-integral (PI) controllers owing to their simplicity of structure and principle [4].…”

Stability and reliability are the most important indicators of drive systems. In this article, a robust nonlinear control method is advanced for dual three-phase permanent-magnet synchronous machine (dual-PMSM) drives, based on the synergetic control theory. This control is implemented by a new synergetic controller (SGC) integrating with an extended sliding mode observer (ESMO), and an optimization method is applied to obtain the optimal parameters of the SGC. This control scheme not only improves the dynamic performance even with operating parameters change, but also can diagnose the speed sensor fault and realize the fault tolerant control (FTC). The proposed control method is compared with the PI control, the sliding mode control (SMC) and the predictive control, as well as the simulation and experimental results confirm the superior dynamic performance and the effectiveness on the speed sensor fault diagnosis (FD) and FTC. INDEX TERMS Synergetic controller, fault diagnosis, fault-tolerant control, speed sensor fault, dual threephase permanent-magnet synchronous machine (dual-PMSM).

“…The fault‐tolerant motor adopts the multiple sets of single‐phase winding to improve the reliability, which has good utilisation of phase winding, high rate of fault tolerance and strong fault isolation [9–11], whereas, the fault tolerant control is complex with a high computation burden and the H‐bridge power inverter required for each phase increases components and costs. The redundant motor utilises multiple sets of three‐phase windings to enhance the reliability, which has a simpler control structure and much easier implementation [12–14]. As a result, the redundant motor system has been widely applied in the aircraft actuation system.…”

This study proposes an optimisation approach of high torque density with guaranteed anti‐short‐circuit performance for the dual redundant permanent magnet synchronous motor (PMSM) in an aerospace application. The 10‐pole/12‐slot dual redundant PMSM with concentrated single‐layer windings is firstly proposed, which can restrain the short‐circuit current by the slot design to increase the phase inductance. Since the anti‐short‐circuit design may result in the torque density degradation of the dual redundant PMSM, the influence of the slot parameters on the torque performance of the dual redundant PMSM is thoroughly investigated, including the electromagnetic torque, braking torque, and no‐load torque. Furthermore, the genetic algorithm‐based optimisation method is proposed to maximise the torque density of the dual redundant PMSM, while the anti‐short‐circuit performance can also be guaranteed. Simulation and experimental results are conducted to verify the effectiveness of the proposed optimisation method.

“…The existing motor position detecting methods can be classified into two types: the high‐frequency signals injection method and the model‐based method. The first one is suitable for the low‐speed operation and independent of the model parameters [12, 13]. However, the injected high‐frequency signals will produce more losses and torque ripple.…”

In this study, a novel sensorless control of the surface‐mounted permanent‐magnet synchronous motor (PMSM) is proposed. Firstly, by taking the derivative of the back electromotive force (EMF), the high‐order voltage equations of PMSM, in which the dominant time‐changing parts of back‐EMF are separated and modelled, are deduced. Then a generalised extended state observer, which possesses the preferable tracking ability for time‐varying states, is designed to estimate the back‐EMF. Also, since the difference between the measured stator resistance and its real value, which changes with temperature, will lead to position errors, a resistance estimation scheme is proposed. Compared with the conventional sensorless method of PMSM, the proposed method can provide a more accurate and smooth position and speed estimation under resistance uncertainty without extra filter and compensator. Furthermore, since the effects of speed and current change rate are taken into consideration, the application of the proposed scheme is broadened. The effectiveness of the proposed method is verified by the experiments in different cases.
