Abstract (en)
Method for controlling the turning of a hydrofoil (1), such method providing for: a first step for detecting a required turn angle (a) and a generation of a corresponding turn signal (SV); a step for detecting the variations of linear acceleration, the variations of angular speed, the tilts and the advancing speed of the hydrofoil (1) and a generation of corresponding acceleration signals, angular speed, tilt and linear speed (SA, SVA, SI, SVL); a first calculation step, as a function of the turn signal (SV), of an ideal turn position (PVI) for each appendage (4) of the hydrofoil (1); a second calculation step, as a function of the acceleration signals, angular speed, tilt and linear speed (SA, SVA, SI, SVL), of first corrective factor (FC1) for each appendage (4); a processing step, in which each ideal turn position (PVI) is corrected by the first corrective factor (FC1) in order to obtain a corrected turn position (PVC) for each said appendage (4); a step for driving first actuator means (5) to move each appendage (4) around a corresponding first rotation axis (Y) in order to reach the corresponding corrected turn position (PVC).
