Non-contact detection method for pantograph-catenary contact force based on image processing
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid TransitThis paper introduces a non-contact method for detecting contact force between pantograph and catenary (PAC), based on image processing and Kalman filter. A non-contact method for detecting contact force of PAC, which only utilizes the vertical displacement of the collector head, is proposed.

Influence of pantograph suspension characteristics on the contact quality with the catenary for high speed trains [PDF]
Computers and Structures, 2012 In general the electrical energy is provided to the trainsets by the pantograph-catenary contact. The study of this system contributes to decrease the number of incidents and the maintenance and interoperability costs.

Comparison of optical and electrical measurements of the pantograph-catenary contact force
SPIE Proceedings, 2010In railway engineering the monitoring of contact force between pantograph and catenary gives information about the interaction between the two systems and it is useful to check the status of the overhead line. Indeed the failure of the catenary is one of the main causes of out of order problems.

Robust Control of Contact Force for Pantograph-Catenary System
2018 57th Annual Conference of the Society of Instrument and Control Engineers of Japan (SICE), 2018To improve the quality of the current collection transmitted to a high-speed train, based on a pantograph model with a three-degree of freedom, two methods are presented to suppress the vibration of the pantograph-catenary system. One is $H_{\infty}$ robust control, and the other is improved equivalent-input-disturbance (IEID)-based control. For the

A robust control of contact force of pantograph-catenary for the high-speed train
2013 European Control Conference (ECC), 2013In 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.

Active nonlinear partial-state feedback control of contacting force for a pantograph–catenary system
ISA Transactions, 2019In this paper, a nonlinear partial-state feedback control is designed for a 3-DOF pantograph-catenary system by using backstepping approach, such that the contacting force of the closed-loop system is capable of tracking its reference profile. In the control design, the pantograph-catenary model is transformed into a triangular form, facilitating the ...

With rising of the running speed of the train, the variation of pantograph–catenary contact force (PCCF) signal increases and the current collection quality between pantograph and catenary becomes worse. In order to explore the ways to optimize the PCCF signal, localization analysis of the value and the change of PCCF signal at the dropper-point are ...

The high-speed train is typically powered by the catenary wire suspended from poles or towers along the rail. An important issue of the high-speed train's power supply is how to set the precise contact force between the pantograph and catenary wires in real time.
