  • Method and means for a regulator for the servo control of a marine craft
    Patent number: 4757243
    Abstract: Method and means for a regulator for the servo control of a marine craft, for instance a torpedo, with variable speed and angle of attack. A first sensor (1) monitors the angle of attack, while a second sensor (8) monitors the depth of the craft. A revolution counter (3) and a filter (4) create an acceleration-compensating signal which is subtracted from an angle-of-attack signal emitted by the first sensor (1), whereupon the signal is transmitted to a rudder servo system.
