Abstract
System for reducing wave and wind induced roll motion of a ship intended to be connected into the regular control system of the ship comprising a rudder motor (SG) for driving the rudder of the ship, which rudder is used both as steering means and for generating a rolling moment, said system comprising a central unit (C) which receives rudder angle signals from a steering wheel (H) and which central unit emits rudder driving signals to the rudder motor (SG) in response to said control and rudder angle signals. The central unit (C) comprises a roll sensor (RS) for generating a roll angle velocity signal ( PHI ) which is brought to an adaptive discrete filter (F) for generation of reconstructed state variables for sampled roll angle velocity ( PHI (n)) and sampled roll acceleration ( PHI (n)) which by reconstruction in the filter estimated state variables ( PHI (n), PHI (n)) are transferred to a predicting regulator (RG) for the rudder angle whereby said regulator in response to the filtered roll angle velocity signals generates a rudder driving signal to the rudder motor (SG) which gives the ship a roll moment of such amplitude and phase that the roll moment induced by wind and waves of the ship is substantially neutralized.
