Correct diagnosing analog circuit fault is beneficial to the circuit's health management, and
its core challenge is extracting essential features from the circuit's output signals. Wavelet …

This paper presents a speed estimation scheme by combining a second-order sliding-mode
observer (SMO) with the model reference adaptive system (MRAS) in the sensorless-vector …

This study presents a comprehensive review of the automated classification in partial
discharge (PD) source identification and probabilistic interpretation of the classification …

The magnetic levitation (MAGLEV) train uses magnetic field to suspend, guide, and propel
vehicle onto the track. The MAGLEV train provides a sustainable and cleaner solution for …

Electromagnetic suspension (EMS) is an important type of maglev train systems. With
commercial success in the low-speed maglev train, developing a medium-speed maglev …

The high-speed maglev train is a new type of transportation. The long stator track plays a
critical role in the levitation guidance and traction system. Therefore, its condition directly …

In power electronics and power systems, the dual-phase-locked loop (DPLL) is a well-
accepted approach to maintain zero steady-state errors when subjecting to a frequency …

This work provides a new approach for modeling the electromagnets of the magnetic
levitation (Maglev) vehicle Transrapid intending to effectively and efficiently represent the …

Maglev trains attracted to suspend above tracks without mechanical contact is a promising
type of track transportation. Suspension choppers with levitation magnets resembling …

In most motor drive applications, the speed sensor is of concern because it potentially
deteriorates the system reliability and increases the system cost. To mitigate the adverse …
