Train Speed Control in Moving-Block Railway Systems: An Online Adaptive PD Controller Design

Since the overall capacity of railway lines are not used effectively in fixed-block railway systems, moving-block railway systems are introduced to increase the transport capacity and to reduce the headway times. CBTC (Communication Based Train Control) systems and ERTMS (European Rail Traffic Management System) application level 3 are regarded as examples of moving-block systems. In this study, the concept of moving-block system is explained and an adaptive PD control technique based on Online Least Square Support Vector Regression is used for train speed control.
