As adhesion coefficient of high speed train (HST) varies with wheel-rail surface condition and running speed, it is thus rather difficult to obtain its accurate value via online measurement, making it non-trivial to design and implement traction/braking control scheme for HST. In this paper, force observers are developed to estimate the adhesion force and the resistance, respectively. Traction/braking...
Antiskid is an important factor that directly impacts safe operation of high-speed trains (HST). However, if the antiskid control is designed independently from the traction/braking unit, as usually the case in most existing methods, the traction/braking control performance might be degraded. In this work, the antiskid constraint is directly linked with the development of traction/braking control...
