Abstract
A fuzzy control that uses rules based on a skilled human operator's experience is applied to automatic train operations. Essentially, train operation is a nonlinear control function. Up to now, this system has been developed by linearlized control usina a target pattern. However, it was difficult to control the train in a manner similar to a human operator. In this paper, a fuzzy control which uses linguistical control rules is proposed. Furthermore, an automatic train operation system which evaluates safety, comfort, traceability of target velocity, and the accuracy of a stop gap has been developed. According to the result of the simulation, our newly developed automatic control system having the fuzzy control realizes a comfortable and accurate stop control, and its control rules are easy to understand and are connected to the performance indices. Therefore, system performance can be directly adjusted as desired.
