Antilock Braking System (ABS) is an automobile safety system. Antilock braking systems are used in modern cars to prevent the wheels from locking after brakes are applied. The vehicle is provided with the controller to control the necessary torque to maintain optimum slip ration. The dynamics of the controller needed for antilock braking system depends on various factors. It’s an automated system that run on principles of threshold braking and cadence braking which were practiced by skillful drivers with previous generation braking system. Its response time is faster hence that makes it easy steering for the driver. The vehicle model often is in nonlinear form. Controller needs to provide a controlled torque necessary to maintain optimum value of the wheel slip ratio. ABS generally offer advanced vehicle control and minimize the stopping distance. The slip ratio is represented in terms of vehicle speed and wheel rotation. In present work first of all system dynamic equations are explained and a slip ratio is expressed in terms of system variables namely vehicle linear velocity and angular velocity of the wheel. By applying a bias braking force system, response is obtained using Simulink models. Using the linear control strategies like P - type, PD - type, PI - type, PID - type the effectiveness of maintaining desired slip ratio is tested. It is always observed that a steady state error of 10% occurring in all the control system models.
