Abstract

In this paper a new method based on multistage fuzzy control using intelligent ‎optimization techniques is proposed to optimize the AUTOMATIC TRAIN CONTROL system. In ‎this method the energy function which elaborates the train power consumption is first ‎minimized by applying Kuhn Tucker conditions. As a result the switching points at ‎which the control strategies are changed between acceleration coasting constant speed ‎and braking are determined considering the track specifications including gradients ‎and curvatures as well as the practical train model. Since in constant speed strategy ‎the energy optimization leads to infinite changes in control inputs which is not ‎practically possible a multistage fuzzy control based on fuzzy dynamic programming ‎with fuzzy termination time is incorporated to overcome this difficulty. Multistage ‎fuzzy control will optimize other significant goals involving safety traceability in ‎speed and accuracy in distance and limit the number of switching among different ‎strategies. Hence the method will satisfy the practical requirements. This method ‎considers the running time between two stations as independent and controllable ‎variables therefore the calculated strategies are very useful and appropriate for traffic ‎control which the time regulations make a vital and important role. The simulation ‎results will demonstrate the efficiency of proposed method.‎
