Special Issue Information

Dear Colleagues,

Due to their high efficiency and high power‒density, permanent magnet synchronous machines (PMSMs) are increasingly being employed in numerous areas of electricity system including wind power generation, flywheel storage, industrial compressors, etc., as either power generation or consumption apparatus. As the power capacity of PMSM-driven electricity systems develop, they have posed more and more challenging requirements of efficiency, power/torque density, and reliability for PMSM drive systems. Research on PMSM-driven electricity system are attracting increasing attention.

To improve the performances of PMSM-driven electricity systems, advanced techniques and methods on both the component- and system-level requirements are arising. For the machine side, high torque-density PMSMs based on magnetic modulation theory, high-speed PMSMs with high power density, and PMSMs with hair-pin windings are being extensively investigated, as well as associated multi-physics modeling and optimization, cooling, and manufacturing techniques. High-performance control methods such as direct torque control, predictive control, sensorless control, and efficiency-optimized control are also being continuously developed. As for the power electronic converter, wide-bandgap (WBG), e.g., silicon carbide (SiC) and gallium nitride (GaN), converters are increasingly researched and regarded as the future trend. To enhance the reliability, condition monitoring techniques become important and fault-tolerant topologies and control of PMSM drives are needed for safety‒critical applications. Additionally, the interaction between the power electronic converter of PMSM drives and the grid have gained special attention, as the stability of grid may be significantly affected by the control of a grid-interfaced converter of PMSM. In addition, other than the conventional back-to-back voltage source converter (VSC), a variety of power converter topologies, e.g., matrix converter and current source converter could be used for PMSM-driven electricity systems. They may demand particular analysis, design, and control methods.

This Special Issue aims to promote research and invites original works in the area of permanent magnet synchronous machine-driven electricity system.

A permanent magnet synchronous motor (PMSM) is a nonlinear, strongly coupled, controlled object with time-varying, fractional-order characteristics. It is difficult to achieve the ideal control effect by using the traditional control method when motor parameter changes and load perturbations occur during the operation of the PMSM, so a fractional-order adaptive fuzzy backstepping control method is proposed to improve the system’s fast response and anti-jamming ability in the case of sudden changes in rotational speed, load perturbations and other conditions. Initially, the fractional order theory is introduced, backstepping control is utilized to decompose the system into multiple subsystems, and a fractional order-based Lyapunov function is designed for each subsystem to ensure the system’s stability. Suitable control laws, as well as parameter adaptive laws, are derived through rigorous mathematical derivation. Finally, a fractional order adaptive fuzzy backstepping controller (FOAB-FPID) is designed by combining the advantages of fuzzy control. Then a mechanical simulation model of the PMSM is established to verify the validity of the designed controller, followed by three sets of comparative experiments: PID, fuzzy PID (F-PID), and integer-order adaptive fuzzy backstepping (IOAB-FPID), which are selected to simulate the PMSM under the control of the four controllers. Finally, it is validated on the constructed PMSM experimental platform. Simulation and experimental results show that FOAB-FPID can adaptively adjust system parameters during sudden speed changes, achieve real-time speed tracking, and maintain speed stability under load perturbations and internal parameter uptake. Compared with the three control strategies, reached PMSM system has better acceleration, fast response performance, and better anti-disturbance ability, which proves the rationality and effectiveness of the FOAB-FPID control method.

With the widespread application of permanent magnet synchronous motor (PMSM) drives, the demand for safety and reliability has increased. Inverter open-circuit fault is a frequent and severe failure that requires reliable detection and remedial measures. This paper proposes an open-circuit fault diagnosis technique based on voltage residual analysis that does not require additional voltage sensors. The proposed technique analyzes the characteristics of the reference voltage and the actual output voltage under both healthy and fault conditions. To achieve fast and reliable fault detection, it uses the DC component and second harmonic component in the residual voltage between estimated voltage and controller reference voltage. Once an open-circuit fault is detected, the polarity of the DC component is capable of identifying the fault location. The effectiveness and robustness of the proposed technique are verified through simulations and testing on a triple redundant PMSM under various load and speed conditions. Full article
