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 ...
