This paper deals with a Fuzzy Logic Controller (FLC) for an automated train braking system. The response of the system will be simulated by using Fuzzy Logic Toolbox in VHDL. The intelligence for braking is provided by a fuzzy logic controller. The fuzzy logic controller is simulated using VHDL. VHDL is a general-purpose programming language optimized for electronic circuit design. The proposed fuzzy logic controller helps in reduction of manpower for the train operation. Here our interest is to stop a subway train that is approaching a station. We wish that the braking system is automatically activated as the train nears its halt point. For the braking system to be activated, the brakes controller is supplied with two inputs: current speed of the train and the distance from the halt point on the station.
