Output Feedback Control of Pantograph-Catenary System

IFAC Proceedings Volumes, 2013
Abstract Controlling the contact force between the pantograph and the catenary has become a requirement for improving the performances and efficiency of high-speed train systems. Indeed, these performances may considerably be reduced because of the catenary equivalent stiffness variation.

An investigation of pantograph parameter effects for pantograph-catenary systems

2014 IEEE International Symposium on Innovations in Intelligent Systems and Applications (INISTA) Proceedings, 2014
The pantograph and the catenary perform the current collection process in electrical railway systems. In such systems, the main purpose is to improve the quality of current collection. Many factors and parameters can affect the interaction between the pantograph and the catenary.

Sensitivity analysis of pantograph-catenary system model

2012 IEEE 5th India International Conference on Power Electronics (IICPE), 2012
The contact wire experiences a dynamic force from the pantograph mechanism which results in the vibrations in the contact wire. A mathematic model between displacement of contact wire and force is developed. The displacement and dynamic force vary with the parameters of pantograph mechanism.

Hybrid Simulation of Dynamics for the Pantograph-Catenary System

Vehicle System Dynamics, 2002
Summary In order to examine the static and dynamic behavior of the pantograph-catenary system, a special teat facility is established and described in this paper. Since the catenary is difficult to be modeled by a hardware teat facility indoor, a mixed theoretical-experimental technique is introduced, in which the pantograph is an actual one but the ...

A nonlinear state feedback control approach for a Pantograph-Catenary system

2013 17th International Conference on System Theory, Control and Computing (ICSTCC), 2013
In this paper, a nonlinear approach is proposed for the control and state estimation of the Pantograph-Catenary system in order to maintain the contact force at a constant level. Assuming that the measures of the contact force and the train velocity are both available, we estimate the states by means of a robust nonlinear observer constructed by the ...

Adaptive-robust polynomial control for the pantograph-catenary positioning system

2018 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR), 2018
This paper deals with the design of a polynomial RST control for a pantograph-catenary (PAC) system. The process of controlling the pantograph-catenary system is of importance for high speed trains. The objective of this work is to propose a simple to implement control method with a high degree of robustness.

Basic Analytical Study of Pantograph-catenary System Dynamics

Vehicle System Dynamics, 1998
SUMMARY For a high speed electrical rail system, good dynamic performance of the pantograph-catenary system is vital for smooth and continuous current collection. It has been known for many years that to achieve this the head of the pantograph should be made as light as possible and the average stiffness of the catenary should be high.

A model predictive control approach for the Pantograph-Catenary positioning system

2012
The paper deals with the predictive control synthesis for a Pantograph-Catenary (PAC) system. The main difficulty of the control design resides in the time-varying characteristics of the dynamics modeled by a chain of spring-mass elements.

Design and study of active controllers for pantograph-catenary system

2014 IEEE Conference and Expo Transportation Electrification Asia-Pacific (ITEC Asia-Pacific), 2014
Pantograph-catenary contact (interface) is the most crucial link to supply electrical power to loco drive. At high train speed, the loss of contact may occur due to the vibrations between the pantograph and catenary. In this paper, the fuzzy logic control is applied to minimize the vibrations in the force using different membership functions using ...
