Fuzzy Control. 0. Replaces mathematical approximations with a fuzzy system. 0. Rules define actions for specific conditions. 0. Biggest application area of fuzzy logic. 0. Examples. – Inverted pendulum. – Sendai subway system. – Washing machines. Inverted Pendulum. 0. Classic fuzzy control application. 0. Task is to By using fuzzy logic control, the control rule that represents the prediction of the future state gained from the experience of operator is evaluated and the best control instruction is selected. The result of this application to a train auto- matic stop control (TASC), which requires complex con- trol for train operation, is described. One of the most famous applications of fuzzy logic is that of the Sendai Subway system in Sendai, Japan. This control of the Nanboku line, the subway went into operation in 1988. For more information on this see: sipi.usc.edu/~kosko/Scientific%20American.pdf(pdf) or www.smart.sunderland.ac.uk/f_succ.htm. has fuzzy logic significantly enhanced knowledge-based/expert system technology While designing the subway system at Sendai, Hitachi engineers spent controlled the train. While operating a train, a skilled driver made control decisions based upon his knowledge of conditions of the track and his understanding of the 3. 1.2 Where does fuzzy logic come from? 5. 1.3 What are the main areas of fuzzy logic applications? 9. 2. Basic mathematical concepts of fuzzy sets. 19. 2.1 Fuzzy sets . fuzzy logic and its application to the design of fuzzy controllers. Leonid Reznik .. Subway Sendai Transportation system control (Japan). 1985 First fuzzy The Sendai Subway 1000 series is a rapid transit electric multiple unit (EMU) train type operated on the Sendai Subway Namboku Line in Sendai, Japan. The 1000 series was the world's first train type to use fuzzy logic to control its speed, and this system developed by Hitachi accounts for the relative smoothness of the 14 Nov 1990 Togai InfraLogic, Inc.

Fuzzy logic AND and OR operations are widely used in fuzzy systems. Unlike the binary AND and. OR operators whose operations . train operation for the Sendai subway. Fuzzy Systems Technology: A Brief Overview system in Japan The Fuzzy Logic Concept. The way that people think is inherently fuzzy. The way that we perceive the world is continually changing and cannot always be defined in true or false statements. Take for example the set of all the apples and all the apple cores in the world. Now take one of those apples; it belongs to the set of all control of a subway in Sendai, Japan, to a fuzzy system (Fig.2.1). Fuzzy control techniques were used in all the critical operations of the train's control system, such as accelerating, breaking, and stopping operations [6] but also in traffic planning and predicting customer's usage of subway facilities.
