Dynamics of the Pantograph-Catenary System
2019Pantograph-catenary interaction is a critical issue for electrified railway systems, as it represents a limiting factor for the maximum speed at which the electric rolling stock can be operated and, at the same time, strongly affects the reliability, availability and maintainability of both the rolling stock and the infrastructure.

Sensitivity analysis of pantograph-catenary system model
2012 IEEE 5th India International Conference on Power Electronics (IICPE), 2012The 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, 2002Summary 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 ...

Hough transform and thermo-vision for monitoring pantograph-catenary system
Proceedings of the Institution of Mechanical Engineers, Part F: Journal of Rail and Rapid Transit, 2006The pantograph-overhead contact wire system is investigated by using an infrared camera. As the pantograph has a vertical motion because of the non-uniform elasticity of the catenary, in order to detect the temperature along the strip from a sequence of infrared images, a segment-tracking algorithm, based on the Hough transformation, has been employed.

A nonlinear state feedback control approach for a Pantograph-Catenary system
2013 17th International Conference on System Theory, Control and Computing (ICSTCC), 2013In 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 ...

Takagi-Sugeno Control Approach for Pantograph-Catenary Positioning System
2019 23rd International Conference on System Theory, Control and Computing (ICSTCC), 2019This paper deals with a non-linear control method based on Takagi-Sugeno representation for a pantograph catenary system. It can be observed that on the subject of railway transportation there is a lot of ongoing research, especially for high speed transportation.

Adaptive-robust polynomial control for the pantograph-catenary positioning system
2018 IEEE International Conference on Automation, Quality and Testing, Robotics (AQTR), 2018This 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, 1998SUMMARY 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
2012The 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.
