Optimal Design of Gap Sensor for High-Speed Maglev Train
Abstract The gap sensor plays an important role in high-speed maglev train which is able to measure the variation of trains’ suspension gap. The magnetic fields distribution is different clearly when the sensor is opposite to different position in a tooth-groove period of stator railway.

Sliding‐Mode Control of Electromagnetic Suspension Systems Considering Disturbance Compensation
This study proposes an integrated control strategy for magnetic levitation systems, combining a cascaded linear extended state observer with an improved sliding‐mode control. This method accurately estimates and compensates for disturbances, significantly enhancing suspension stability and rejection capability.

In this paper, a 3D multi‐source GBSM model is proposed for the vacuum tube scenario using LCX. By equating the periodic slots to multiple magnetic dipole antennas, the electric field distribution of LCX is deduced, and the CIR expression is derived. Based on this, the multi‐link spatial‐temporal correlations, including the spatial CCF and temporal ACF,

This paper proposes a novel power loss reduction PWM (PLRPWM) strategy for three‐level neutral point clamped inverters. The proposed strategy aims to achieve multi‐objective optimisation by balancing low output harmonics, reduced switching losses and a balanced neutral‐point potential. ABSTRACT Three‐level neutral point clamped (3L‐NPC) converters have

Bibliometric Analysis of Transport Infrastructure Hypernetwork: Review and Prospects
The transport infrastructure is transitioning into a multilayer, multifunctional hypernetwork form, posing challenges to traditional single‐mode planning methods in analyzing cross‐system risk transmission mechanisms and achieving spatiotemporal resource optimization. This leads to suboptimal system synergy and resilience.

In this work, we study the β‐fractional multicomponent Gross–Pitaevskii (G–P) system, which plays an important role in modeling Bose–Einstein condensates (BECs) and propagation in nonlinear waves. In Bose–Einstein condensation, the G–P equation is of great importance as it describes the condensate wave function’s behavior.

ABSTRACT Time delays frequently arise in active control systems due to sensor sampling, signal transmission, and actuator response, making their effects on system dynamics non‐negligible. This paper investigates how velocity feedback time delay influences the nonlinear dynamic characteristics of a maglev train subjected to unsteady aerodynamic forces ...
