Human-in-the-loop COLREGs-compliant platoon formation control of maritime autonomous surface ships via finite state machine (opens in a new tab)
This study presents a control system for maritime autonomous surface ships (MASSs) that integrates human supervision into platoon navigation while adhering to COLREGs collision avoidance rules. A virtual leader allows human operators to adjust the platoon’s speed, while a finite state machine identifies encounter scenarios and applies safety constraints via control barrier functions. The system uses a cooperative path-following guidance law and quadratic optimization to balance collision avoidance with platoon coordination. Simulations confirm the approach effectively maintains formation and complies with maritime safety regulations.
