Abstract

Brushless direct-current (BLdc) motors are pivotal in electric vehicles, drones, and industrial systems due to their high efficiency and reliability. However, faults in stators, rotors, or inverters may degrade performance. In this article, we focus on the problem of model-based fault detection of BLdc motors. First, a high-fidelity model of the BLdc motor is developed, explicitly incorporating inverter switching behaviors, winding, back EMF, rotor inertia, and Hall sensors, which is formulated as a discrete-time-varying descriptor system. Based on this model, a fault detection method is proposed using a set-membership estimation theory. The proposed BLdc motor model has higher fidelity, and the fault detection method has more relaxed design conditions. Finally, a hardware-in-the-loop (HIL) platform, including a BLdc motor, is established. After that, the platform is used to validate the fidelity of the proposed BLdc motor model and the effectiveness of the fault detection method.
基于广义系统集隶属度估计的无刷直流电机故障检测
无刷直流(BLdc)电机由于其高效率和可靠性在电动汽车,无人机和工业系统中至关重要。但是,定子、转子或逆变器的故障可能会降低性能。本文主要研究基于模型的无刷直流电机故障检测问题。首先,建立了无刷直流电机的高保真模型,明确地结合了逆变器开关行为、绕组、反电动势、转子惯性和霍尔传感器,并将其表述为离散时变广义系统。在此基础上,提出了一种基于集隶属度估计理论的故障检测方法。所提出的无刷直流电机模型具有更高的保真度,故障检测方法具有更宽松的设计条件。最后,建立了包括无刷直流电机在内的硬件在环(HIL)平台。然后,利用该平台验证了所提出的无刷直流电机模型的保真度和故障检测方法的有效性。

期刊介绍: The IEEE Transactions on Control Systems Technology publishes high quality technical papers on technological advances in control engineering. The word technology is from the Greek technologia. The modern meaning is a scientific method to achieve a practical purpose. Control Systems Technology includes all aspects of control engineering needed to implement practical control systems, from analysis and design, through simulation and hardware. A primary purpose of the IEEE Transactions on Control Systems Technology is to have an archival publication which will bridge the gap between theory and practice. Papers are published in the IEEE Transactions on Control System Technology which disclose significant new knowledge, exploratory developments, or practical applications in all aspects of technology needed to implement control systems, from analysis and design through simulation, and hardware.
