Indirect economic effects of a rail link along the afsluitdijk [PDF]
, 2002 New transport infrastructure has a myriad of short and long run effects. The effects on population and economic activity are most difficult to estimate. This paper introduces three different models to estimate the impacts of new infrastructure on labour ...

Sliding‐Mode Control of Electromagnetic Suspension Systems Considering Disturbance Compensation
IET Intelligent Transport Systems, Volume 20, Issue 1, January/December 2026.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.

Research on sliding mode controller of high-speed maglev train under aerodynamic load [PDF]
, 2021 Abstract Maglev train is suspended through the surrounding track, which overcomes manydisadvantages caused by the direct contact between the wheel and rail oftraditional vehicles, such as excessive friction. It has the advantages of high speed,comfortable riding, less maintenance, strong climbing ability, and so on.

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.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,

Optimal Design of Gap Sensor for High-Speed Maglev Train
IOP Conference Series: Materials Science and Engineering, 2019 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.

IET Power Electronics, Volume 19, Issue 1, January/December 2026.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

International Journal of Mechanical System Dynamics, Volume 5, Issue 4, Page 707-720, December 2025.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 ...
