This paper presents a technique for improving the performance of active steering fuzzy control systems by adequately changing the widths of triangular fuzzy membership functions. Running curve railway, the wheelsets of conventional vehicles generally misalign radically with the track increasing wheel/rail contact forces and resulting in increased wheel and rail wear. To solve these problems, modified suspension system designs, application for alternate wheel profiles, active and semi-active steering techniques have been proposed. Active steering system has proven its ability to bridge the gap between stability and curve friendliness. Experiment results show that the proposed fuzzy controller robustly yields good performance comparing with conventional controller.
