Abstract—Numerous uncertainties in practical production and operation can seriously affect the drive performance of permanent magnet synchronous machines (PMSMs). Various robust control methods have been developed to mitigate or eliminate the effects of these uncertainties. However, the robustness to uncertainties of electrical drive systems has not been clearly defined. No systemic procedures have been proposed to evaluate a control system's robustness (how robust it is). This paper proposes a systemic method for evaluating control systems' robustness to uncertainties. The concept and fundamental theory of robust control are illustrated by considering a simple uncertain feedback control system. The effects of uncertainties on the control performance and stability are analyzed and discussed. The concept of design for six-sigma (a robust design method) is employed to numerically evaluate the robustness levels of control systems. To show the effectiveness of the proposed robustness evaluation method, case studies are conducted for second-order systems, DC motor drive systems, and PMSM drive systems. Besides the conventional predictive control of PMSM drive, three different robust predictive control methods are evaluated in terms of two different parametric uncertainty ranges and three application requirements against parametric uncertainties.

摘要—实际生产和运行中的许多不确定性会严重影响永磁同步电机（PMSM）的驱动性能。为了减轻或消除这些不确定性的影响，人们开发了各种鲁棒控制方法。然而，电气驱动对不确定性的鲁棒性尚未得到明确定义。目前还没有提出评估控制系统鲁棒性（鲁棒性如何）的系统程序。本文提出了一种评估控制系统对不确定性的鲁棒性的系统方法。通过考虑一个简单的不确定反馈控制系统来说明鲁棒控制的概念和基本理论。分析并讨论了不确定性对控制性能和稳定性的影响。采用六西格玛设计概念（一种鲁棒设计方法）对控制系统的鲁棒性水平进行了数值评估。为了证明所提出的鲁棒性评估方法的有效性，对二阶系统、直流电机驱动系统和 PMSM 驱动系统进行了案例研究。除了 PMSM 驱动器的传统预测控制外，还针对参数不确定性的两种不同参数不确定性范围和三种应用要求评估了三种不同的鲁棒预测控制方法。

Z. Chen, X. Lin, H. Ji, Z. Li, H. Zhao and D. Xiao, "Enhanced sensorless control of switched reluctance motors using inertial phase-locked loop for extended speed range," in CES Transactions on Electrical Machines and Systems, doi: 10.30941/CESTEMS.2025.00013.

Abstract—Sensorless control of switched reluctance motors (SRMs) often requires a hybrid mode combining low-speed pulse injection methods and high-speed model-based estimation. However, pulse injection causes unwanted audible noises and torque ripples. This article proposes an enhanced model-based sensorless approach to extend downwards the speed range in which sensorless control can work without injection. An inertial phase-locked loop (IPLL) based on a stator flux observer is introduced for position estimation. Compared to the conventional phase-locked loop scheme, the IPLL offers a more robust disturbance rejection capability and thus reduces the flux model errors at lower speeds. Experimental results substantiate the feasibility of the extended low-speed operation using the model-based sensorless control approach.

摘要—开关磁阻电机（SRM）的无传感器控制通常需要结合低速脉冲注入方法和高速基于模型的估计的混合模式。然而，脉冲注入会导致不必要的可听噪音和扭矩波动。本文提出了一种增强的基于模型的无传感器方法，用于无传感器控制在没有注入的情况下，向下扩展速度范围。介绍了一种基于定子磁链观测器的惯性锁相环（IPLL）用于位置估计。与传统的锁相环方案相比，IPLL提供了更鲁棒的干扰抑制能力，从而减少了低速下的通量模型误差。实验结果证实了使用基于模型的无传感器控制方法进行扩展低速运行的可行性。

Y. Chen, D. Tao and B. Ge, "Additional magnetic field of dual-parallel rotor permanent magnet synchronous motor and its influence on electromagnetic torque," in CES Transactions on Electrical Machines and Systems, doi: 10.30941/CESTEMS.2025.00015.

Abstract—The coupling effect of dual-parallel rotor connected stator permanent magnet synchronous motor not only affects the magnetic field in the coupling area, but also generates an additional magnetic field in the uncoupled area. The characteristics of the additional magnetic field and its influence on electromagnetic torque are studied in this paper. The topology and parameters of motor are described briefly. The existence of additional magnetic field is proved by the simulation models under two boundary conditions, and its characteristics and source are analyzed. The analytical model is established, and the influence of key parameters on the additional magnetic field is discussed. On this basis, the influence of the additional magnetic field on the electromagnetic torque of the motor is studied, and the analytical expression of the additional torque is constructed. The fluctuation rule is analyzed, and the additional magnetic field separation model is proposed. The theoretical analysis and simulation results reveal and improve the internal mechanism of reducing motor torque ripple by optimizing the duty angle and coupling distance. Finally, a prototype test platform is built to verify the correctness of the proposed theory and the accuracy of the simulation model.
