Adaptive Control of Pantograph-Catenary Interaction Force
Authors: , ,
Abstract: The catenary and the pantograph of an electric locomotive have a dynamic-oscillatory behavior, to which are added a series of turbulences that cannot be approached by a classic calculation method. Experimental observations and reference literature point out the fact that at speeds higher than 180 km/h, the pantograph and the catenary temporarily lose contact and that triggers electric arcs with negative consequences. Some mathematical models have been developed, predicting the dynamic behavior of this assembly and of the contact force, but all of them have some degree of imprecision (disregarding the phenomena difficult to model). They also can not be used in real time to control the contact force between the pantograph and catenary. This paper suggests a new method thereby the system that controls the contact force is divided into two sub-systems: a determinative one and a chaotic one; for each one, appropriate adjustment laws are suggested. The solutions resulting from simulation are encouraging and need industrial implementation.
