Real-Time Look-Ahead Distance Optimization for Smooth and Robust Steering Control of Autonomous Vehicles [PDF]
2021 29th Mediterranean Conference on Control and Automation (MED), 2021 This paper presents an optimization problem for the look-ahead distance used in lateral automated vehicle control. A relation is formulated to describe the sensitivity of the control input steering speed $\dot \delta $ with respect to the variation of the look-ahead distance L.

Path Tracking Control of a Differential-Drive Tracked Robot Based on Look-ahead Distance
IFAC-PapersOnLine, 2018 Abstract In this paper, a PI path tracking controller based on look-ahead point information for a differential-drive crawler-type robot was developed. The robot is equipped with Global Navigation Satellite System (GNSS) antennas and a receiver module which are used as navigation sensors to obtain real-time estimates of the position and heading errors
