Driver model simulation for railway brake systems

This study proposes an essential issue to construct a driver model for a railway in order to keep a safe and integral society throughout the world. As of now, no study has been made on the transfer function of train drivers and brake systems as to safety of a railway. This paper describes the stability and safety of railway vehicles controlled by train drivers. The driver model used the model as proposed by Iguchi et al., and used the transfer function that consisted of the proportion, differentiation and the integrated operation. This study describes the frequency characteristics: transfer function from a braking command to error between the reference velocity and real velocity. Moreover, overrun distances against driver model parameters are shown. According to the simulation results, an integral gain of the transfer function of the driver model is important in the brake and vehicle dynamics.
