Active steering control of a rail vehicle : a new approach

The object of this investigation was to design, develop and simulate a fuzzy logic controller for an active steering control system of a rail vehicle. The active steering railway bogie is built upon the application of axle boxes with links and actuators inclined to the longitudinal axle of bogie in the horizontal plane. Actuator actions depend on analysis of noise in the wheel-rail contact. The obtained results of performed simulations with a locomotive model running in a curve show the possibility of the application of the proposed design for new rail vehicles and locomotives produced earlier, which have running gear based on Alstom designed constraints.
