A Framework for Vehicle Lateral Motion Control With Guaranteed Tracking and Performance

Abstract

In this paper, we propose a framework to design a controller for the vehicle lateral dynamics, which guarantees to meet desired safety and performance requirement. Bounded lateral deviation from the reference trajectory is the strict safety requirement considered in this paper.The proposed control design relies on a mild assumption. That is, the trajectory planner generates a trajectory that is piece-wise clothoidal (PWC), with bounded curvature and curvature rate.Closed-loop simulations using a linear quadratic regulator (LQR) and a model predictive control (MPC) controller, developed based on the proposed framework, validates the proposed approach.
