Design of an Improved PID Controller for Antilock Braking System (ABS) using Extremum Seeking Algorithm

Abstract

A safety anti-skid braking system known as an anti-lock braking system (ABS) is used on buses, trucks, cars, and motorcycles as well as on airplanes. Modern ABS systems attempt to maximize tire-generated braking forces by keeping the longitudinal slip ratio below a desirable level in addition to trying to prevent wheels from locking. Slip rate is the difference between actual and calculated vehicle speed affects the friction coefficient which varies depending on the road surface mainly used in control of slip. Conventionally, a great number of controllers have been built for ABS, but there is a limitation of maintaining the braking time
