SHIP STABILIZATION SYSTEM Russian patent published in 1998 - IPC

FIELD: accurate stabilization of ships in case of heavy impulsive disturbances arising due to throwing special cargoes from ships. SUBSTANCE: system includes logic unit, depth error sensor, angle-of-trim sensor and list sensor which is connected via first amplifier with input of first actuator whose output is connected to second input of first amplifier. Output of depth error sensor is connected with input of second actuator through second amplifier; output of second actuator is connected to second input of second amplifier. Angle-of-trim sensor is connected via third amplifier with input of third actuator whose output is connected to second input of third amplifier. Output of program setter is connected with control pulse setters and list sensor is connected with second input of first control pulse setter through logic unit. Outputs of control pulse setters are connected with inputs of respective compensating member. EFFECT: enhanced reliability of stabilization. 1 dwg
