DISIRED VALUE SPEED OBEYING SYSTEM BY AUTOMATIC TRAIN CONTROL

摘要

PURPOSE: A target speed tracking control system for an automatic train operation is provided to stop the train at the preset stop position in an accurate and stable manner, while achieving improved efficiency and stability of the train operation. CONSTITUTION: A target speed tracking control system receives command regarding the speed of the train through an automatic train control from a track circuit during the train operation. A jerk profile for permitting the train to shift from the current speed to the target speed is obtained, wherein the jerk profile satisfies both acceleration and jerk limits. Thus-obtained jerk profile is integrated twice, to thereby obtain a speed profile.
