Abstract
An Optimum Fuzzy Controller which is applicable to the optimum operation of train's running is described. In designing the controller, not only the operating experience of skilled drivers can be fully considered, but also the Fuzzy Control Theory can be properly combined with the Optimum Theory. By developing an on-site controller realized by a microcomputer system, field tests had been finished in P.R. of China. As a result, it was testified that the fuel oil consumption was apparently decreased on the premise of safety and punctuality of train's running. In order to make characteristics of the Optimum Fuzzy Controller more perfect, it has been improved with the help of advanced technology and supporting tool of fuzzy control in Japan. The simulation result shows that the improved controller can ensure the train's running in an optimum operating way even though actual disturbances are great.
