Abstract:
A stabilization apparatus for ship movements, comprising:adjustable stabilizers; drive devices to adjust a position of the stabilizers; a control device that produces control signals corresponding to required positions of the stabilizers, the control signals being provided to the drive devices; a first measurement device by which rolling movements of the ship are detected, and measurement signals corresponding to the detected rolling movements are generated and provided to the control device, and wherein said first measurement device a) separately detects as measured variables at least one of: i) roll angle, ii) a roll angle rate, and iii) a roll angle acceleration, and b) separately determines from the measured variables at least one of: i) the roll angle, ii) the roll angle rate, and iii) the roll angle acceleration, so that the control signals produced in the control device in order to compensate for the rolling movements of the ship are formed from at least one of: i) a roll angle component, ii) a roll angle rate component, and iii) a roll angle acceleration component, and further wherein at least one of the roll angle component, the roll angle rate component and the roll angle acceleration component is capable of being preset in the control signals; and a second measurement device by which pitching movements are detected and measurement signals corresponding to the detected pitching movements are generated and provided to the control device, wherein the second measurement device a) separately detects as measured variables at least one of: i) a pitch angle, ii) a pitch angle rate, and iii) a pitch angle acceleration, and b) separately determines from the measured variables at least one of: i) the pitch angle, ii) the pitch angle rate, and iii) the pitch angle acceleration so that the control signals produced in the control device in order to compensate for the pitching movements of the ship are formed from at least one of: i) a pitch angle component, ii) a pitch angle rate component, and iii) a pitch angle acceleration component and further wherein at least one of the pitch angle component, the pitch angle rate component, and the pitch angle acceleration component is capable of being preset in the signal part of the control signal.
