Fuzzy Logic Controller Implementation in ANSI C

This paper outlines the development of software in ANSI C to implement a fuzzy controller. A fuzzy controller can provide control to many different actuators in a vehicle where a mathematical model of a system is vague or highly complex, such as a climate control system. During the design stage, emphasis was placed on memory requirements and computational efficiency due to the fact that the final system was to be implemented on a microcontroller. This paper provides an outline of the choices made along with an overview of the methods and algorithms used to successfully implement the controller.
