Active Control of a High-Speed Pantograph

Journal of Dynamic Systems, Measurement, and Control, 1997
The design and performance of an active controller for a pantograph which collects current for a high-speed train are considered. A dynamic model of the pantograph/catenary system is described and control objectives are established. A design which incorporates a frame-actuated controller and requires only a single measurement is described.

Optimizing active control scheme of high-speed pantograph

2009 IEEE 6th International Power Electronics and Motion Control Conference, 2009
A novel control scheme for the active suspension in a 4-DOFs pantograph is presented here. The concepts of force cancellation, Skyhook damper and track-following spring are jointly applied to establish an active vibration control system. A force cancellation control scheme is used to isolate the sprung masses.

Active Control of Fuzzy for High-Speed Pantograph

Applied Mechanics and Materials, 2012
The regular current collection is very important for high-speed train， and can be obviously improved by the use of active control. In order to study the impact of the fuzzy active control on pantograph-catenary system, the model ohe simulation model is created with the software of simulink.

The French High Speed Train (TGV) Pantograph's Aeroacoustics

SAE Technical Paper Series, 1997
<div class="htmlview paragraph">After 300 kph the aerodynamics noise emitted by the French High Speed Train T.G.V. (Train Grande Vitesse) becomes preponderant. The pantograph and roof environment located in the top of the rear power car are one of the sources which participate in the overall noise of the train. Investigations in an anechoi'c wind

An instrumented pantograph for high speed current collection measurements

4th IET International Conference on Railway Condition Monitoring (RCM 2008), 2008
An instrumented pantograph has been developed by DeltaRail Group Limited that essentially exhibits the same aerodynamic characteristics as a standard high speed pantograph, which should assist engineers undertaking current collection tests and condition monitoring the overhead contact system.

Multiple Pantograph Interaction With Catenaries in High-Speed Trains

Journal of Computational and Nonlinear Dynamics, 2012
The limitation on the top velocity of high-speed trains concerns the ability to supply the proper amount of energy required to run the engines through the catenary-pantograph interface. Due to the loss of contact, not only the energy supply is interrupted, but also arching between the collector bow of the pantograph and the contact wire of the catenary

Active self-adaptive control of high-speed train pantograph

2011 IEEE Power Engineering and Automation Conference, 2011
In this paper, in order to degrade the vibration of contact force between Pantograph and Catenary of high-speed railway, a new solution using Cylindrical Linear Induction Motor as active actuator is proposed. Based on the mathematical model of Catenary presented in the reference papers, the 2-degree Spring-Mass model of Pantograph-Catenary System is ...
