Fuzzy switch of high-speed ATO systems based on running conditions

High-speed Automatic Train Operation (ATO) systems based on running condition is discussed. According to the actual running conditions of the train, the force of the train is different on deriving the dynamic equations of motion of the high-speed ATO systems. Fuzzy rules were used here to control high-speed train running process, thus to switch the running conditions of the train. The result is illustrated to be efficient through the simulation of a certain high-speed train model of EMU.
