Research of Pantograph-Catenary Active Vibration Control System Based on NARMA-L2 Model

Single catenary system model and three-dimensional mass model of pantograph system were established, and kinetic equation was given in this paper. NARMA-L2 neural network model was introduced and applied to the pantograph-catenary vibration control system, and an active control proposal was designed. Simulation research was done as to the effect of controller for speed of 200 km h(-1), 250 km h(-1), and 300 km h(-1). Also the simulation gets pantograph-catenary contact force and pantograph uplift curve, simulation data were analyzed from four aspects maximum, minimum, average, and standard deviation. Comparative results show that compared with the control without NARMA-L2 model, standard deviation of pantograph-catenary contact force and pantograph uplift is lower much at the set speed. Therefore, pantograph vibration control system based on NARMA-L2 neural network can greatly reduce the vibration amplitude of pantograph-catenary and enhanced pantograph-catenary coupling, thus achieved more stable pantograph-catenary contact and better current collection.
