CONTROL SYSTEM FOR A HYDROFOIL WATERCRAFT WITH FULLY SUBMERGED HYDROFOIL

摘要

A stabilized a hydrofoil water craft comprising: a water-craft base member, a hydrofoil mast having proximal and distal portions; said proximal portion mechanically connected to said bottom side of said water-craft base member, a fuselage mechanically connected to said distal portion of said at least one hydrofoil mast, a rudder configured for controlling a yaw angle of said water craft, an elevator rotatable around an axis lying in a plane parallel to water-craft base member and a stabilization arrangement further comprising at least one sensor configured for detecting a 3D orientation of said water-craft base member, an estimator configured for estimating the 3D orientation, actuators for manipulating the rudder and elevator and a controller for analyzing the estimated 3D orientation and controlling the actuators. In response to a disturb roll inclination of the water craft, the controller generates a command to a rudder actuator to compensate the detected inclination.
