IET Cyber-Systems and Robotics, Volume 4, Issue 1, Page 51-60, March 2022., 2022 Abstract This study investigates the integral line of sight (ILOS) path‐following control problem of surface vehicles whose dynamics feature external disturbances, model uncertainties, and actuator dead zones. First, introducing the ILOS guidance law, the path‐following control problem is converted to stabilising a 2nd order nonlinear system ...

Journal of Advanced Transportation, Volume 2022, Issue 1, 2022., 2022 A novel real‐time collision avoidance method for autonomous ships based on modified velocity obstacle (VO) algorithm and grey cloud model is proposed. A typical VO algorithm is used to judge whether there is a collision risk for ships in the potential collision area (PCA).
