A novel path-following control algorithm for surface vessels based on global course constraint and nonlinear feedback technology

Baigang Zhao et al.

Summary: This paper proposes a novel path-following control algorithm for surface vessels based on global course constraint. The algorithm divides the preset path into straight and waypoint segments, designing guidance laws for each to ensure smoother course changes for the ship. Through experiments and analysis using a teaching practice ship, the effectiveness and superiority of the algorithm are further verified.
