ABS system is a common technology which is broadly used in automotive field nowadays. Many researchers put their effort on developing the right controller in order to merge with existing ABS system. This determination led to development of several systems for example the implementations of PIO controller. Under this project, the main objective is constructing or developing an accurate a quarter vehicle traction model with good ABS controller. Significant vehicle behaviour were examined specifically body and wheel speed, tire longitudinal slip and distance travel experience by the vehicle to investigate the behaviour of ABS under influence of PID and the latest development of FGPID controller. Outcome of the validation experiment shows that response between vehicle model and experimental vehicle are match with an acceptable error. As overall, by the ability of the controller in tracking the changes in slip and changes in the velocity of the vehicle, it is verified that the proposed FGPID controller is very suitable to be used as the controller for the ABS system. The previous FOPID then modified to be p 1-a1 1-P o 1-r with the intention to make the controller more efficient, effective and more robust to the changes in parameters and references.
