Active Steering Control System of Scaled Railway Vehicle based on Fuzzy Controller

초록

Running curve railway, the wheelsets of conventional vehicles gen-erally misalign radically with the track increasing wheel/rail contact forces and resulting in increased wheel and rail wear. To solve these problems, modi-fied suspension system designs, application for alternate wheel profiles, active and semi-active steering techniques have been proposed. Active steering sys-tem has proven its ability to bridge the gap between stability and curve friend-liness. This paper describes the development of a fuzzy controller of an active steering control system of 1/5 scaled railway vehicle. Experiment results show that the proposed fuzzy controller robustly yields good performance compar-ing with classic PID controller.
