Output Constrained Control Based Barrier Lyapunov Functions for Lateral Dynamics of Autonomous Vehicles
摘要
This article studies control systems for an automatic lane change system for autonomous vehicles. In this study, a control law is based on a backstepping techniques (BSP) using barrier Lyapunov function (BLF) to constrain the tracking error to be limited within a predefined range and avoid the chattering phenomenon. The slow and fast dynamics of the system are controlled separately by the proposed control technique following the model reduction approach. A conventional sliding mode controller is used as a standard controller to evaluate the proposed controller. Co-simulation based on CarSim and Matlab/Simulink are used to demonstrate the effectiveness and robustness. Performance index of autonomous vehicles such as IWPEI, ITAE, IAPE, and IASE is expressed to quantitatively evaluate the proposed control system.
