Output–Feedback Regulation of the Contact-Force in High-Speed Train Pantographs

Journal of Dynamic Systems, Measurement, and Control, 2004
One of the main problems in high-speed train transportation systems is to counteract the fast variations of the contact force between the catenary and the pantograph collector end. The variation of the catenary equivalent stiffness, due to the suspending system, originates mechanical oscillations whose frequency and magnitude are larger and larger as ...

A robust control of contact force of pantograph-catenary for the high-speed train

2013 European Control Conference (ECC), 2013
In this paper, a simplified model to three degree of freedom (3-DOF) of the pantograph-catenary (PAC) system is represented. A robust control of contact force between the pantograph and the catenary for the high-speed trains using the fuzzy sliding mode controller and the additional compensator is presented.

Simulation and Design of a High Speed railway Pantograph for Trenitalia S.p.A.

2006
The paper deals with the design process undertaken for a proposed high speed pantograph oriented to the interoperability, developed in cooperation among Trenitalia SpA (Italian railway stock holder and manager) and three Italian universities. Aim of the work is the development of an optimized passive pantograph, in which the control of the contact ...

Aeroacoustics source identification and analysis of a high-speed pantograph

Physics of Fluids
Thoroughly comprehending pantograph noise mechanisms and characteristics is crucial for its low noise design, and high-resolution aeroacoustics source identification is the prerequisite for deepening these comprehensions. This study develops an aeroacoustics source identification method based on the integral formulation of the Ffowcs Williams–Hawkings ...
