Manoeuvring and Motion Control of a Hydrofoil
IFAC Proceedings Volumes, 1987 Computer-aided design techniques are described and demonstrated in studies associated with the regulation of pitch, roll, heave and yaw of a 31 m surface piercing hydrofoil. The procedures outlined are effected by way of a comprehensive suite of software for control system data processing which is employed in the transformation of the basic model into ...

Formation Control With Obstacle Avoidance of Underwater Swarms Based on Relative Visual Feedback
Journal of Field Robotics, EarlyView.ABSTRACT Underwater multi‐robot and swarm systems require advanced methodologies for controlling collective behavior. Conventional single‐robot techniques, such as tethering, sonar imaging, and acoustic localization, are not scalable or effective for swarm applications.
