Automatic Car Braking System Using Using Pd Fuzzy Logic Controller

Abstract

This paper deals with an automatic car braking system using Fuzzy Logic Controller (FLC).
The purpose of this controller is to brake a car when the car approaches an obstacle at a
specific range The response of the system will be simulated by using Fuzzy Logic Toolbox in
MATLAB. In this paper, Fuzzy Logic Controller is designed using the Fuzzy Logic Toolbox in
MATLAB and then compared with PI and PD type Fuzzy Logic Controller. The FLC system
designed uses four rules and three membership function. Braking performance will be
observed for each controller type in term of distance and velocity to prevent collision or
accident.
