Abstract
936,627. Automatic stabilization systems for ships. MUIRHEAD & CO. Ltd. Feb. 24, 1961 [March 22, 1960], No. 10157/60. Class 38 (4). In a ship roll or pitch stabilizer control system the algebraic sum of signals derived from potentiometers across generators producing electrical signals linearly proportional to components of roll or pitch is applied to a control amplifier. In Fig. 1 an electrical signal linearly related to the roll angle of a ship is produced by an induction regulator 1 adjusted by a gyro vertical 2. This signal is opposed by the output of an induction regulator 8 driven through reduction gearing 11 by a servomotor 5 controlled by the difference between the signals from induction regulators 1 and 8 so that the difference signal represents the roll angle relative to the mean roll angle. This signal is applied to a potentiometer 13. A signal proportional to rate of roll is produced across a potentiometer 17 from an induction regulator 14 adjusted by a roll rate gyro 16. This signal is also applied to control a velocitydamped follow-up type servomotor 20 which drives a tachometer generator 21 producing a signal proportional to roll acceleration across a potentiometer 22. The signals from potentiometers 13, 17, 22 proportional to roll angle, rate, and acceleration respectively, are combined in suitable proportions, according to the settings of the potentiometers, and applied to a magnetic, thermionic or transistor amplifier 29 controlling stabilizers (not shown) such as fins. The fins operate an induction regulator 26 to produce a positive feedback signal, dependent on fin angle, across a potentiometer 28. This signal is applied to the input of amplifier 29 together with the output of a potentiometer 25 supplied by an induction regulator 23 operated by the ship's steering gear (not shown) to reduce heeling during turn. In a modification the roll acceleration signal is produced by a pair of accelerometers, one on each side of the ship.
