Active front steering system using adaptive sliding mode control

Abstract

This study deals a robust approach to improve vehicle handling manoeuvres and path tracking performance for front steering system of Sport Utility Vehicles (SUVs). The approach used the dynamic sliding mode control based on an integral sliding surface to enhance the robustness of the proposed controller and vehicle handling performance. In this paper, the controller is designed to be insensitive and robust to system uncertainties and disturbances. Its stability analyse based on Lyapunov theory is introduced to ensure the stability of this close-loop control. The results show the effectiveness of the proposed AFS system in yaw stability for SUV via the co-simulation of Matlab/Simulink and CarSim® under double lane change procedure and various road surface conditions.
