Abstract (en)
Method for controlling the position of a hydrofoil (1), such method providing for a detection step, in which at least one flow sensor (6) detects at least one speed measurement of a water flow movable along a transverse direction (F) and generates a corresponding flow signal (SF), a first calculation step, in which an electronic control unit (7) receives the flow signal (SF) and calculates a corresponding difference of lift (ΔP) between a first lift force (P1) of a port appendage (4') and the second lift force (P2) of a starboard appendage (4"), a second calculation step, in which the electronic control unit (7) calculates a movement position (PM) in which each appendage (4) is moved, in which the difference of lift (ΔP) is substantially zero, a driving step, in order to drive the actuator means (5) to move each appendage (4), a movement step in which the actuator means (5) move each appendage (4) in order to reach the corresponding movement position (PM) independently with respect to the other of the two appendages (4).
