Fin stabilizer control device for high-speed craft

摘要

(57) [summary] (modified with) [purpose] when the hull is in a nearly straight state is as like a normal fin stabilizer can reduce the rolling of the hull, properly to heel the boat at the time of turning of the hull It was for perform the balance turning Te. [Configuration] hydrofoil 1 and the blade angle adjusting mechanism 6 is arranged to form a both sides in pairs in the bottom part, the hull of the lateral tilt angle sensor 2a And the detection signal φ from the lateral inclination angular velocity sensor 2b of the hull, based on the dφ / dt, and a normal control system 7 to send a control signal φ ₁ to the blade angle adjusting mechanism 6, also at the time of the hull 10 turning, the steering angle sensor detection signal φ and turning time calculator 8a that calculates a turning time T of the hull based on the _R from the 4, turning radius calculator 8 b and, and the lateral acceleration calculator 8c for computing the lateral acceleration α of the hull on the basis of the turning radius R and the turning time T, turning when the hull horizontal tilt angle calculation to calculate the lateral acceleration α turning when the hull next to the inclination angle θ based on the and vessel 8d, and a command signal calculator 9 hydrofoil are provided by computing the difference between the control signal φ ₁ from turning when the hull heeling angle calculator output signals from 8d θ and normal control system 7 .
