DEVICE FOR CONTROL OF SHIP WITH DIAGNOSIS Russian patent published in 2006 - IPC B63H25/00 G05D1/00 

FIELD: shipbuilding; ship control systems with diagnosis.

SUBSTANCE: proposed device includes trim angle sensors, angular velocity sensors, rudder sensors and trim angle setter whose outputs are connected to first, second, third and fourth inputs of summing-up amplifier whose output is connected with steering gear input. Command unit output is connected with inlet valve of ballast tank through program unit. Device is provided with summing-up amplifier model, steering gear model, program unit model, ballast tank model, ship model, fast time ship model and first-fifth failure indicators. First and second inputs of first failure indicator are connected respectively with summing-up amplifier outputs and with output of summing-up amplifier model. First and second inputs of second failure indicator are connected respectively with steering gear output and steering gear model output. First and second inputs of third failure indicator are connected respectively with outlet valve of ballast tank and outlet valve of ballast tank model. First and second inputs of fourth failure indicator are connected respectively with output of angular velocity sensor and with ship model output whose first and second inputs are connected respectively with outlet valve of ballast tank and output of steering gear model whose input is connected with output of summing-up amplifier model. First and second inputs of fifth failure indicator are connected respectively with output of fast-time ship model and with output of failure indicator setter; outputs of failure indicator sensor, failure indicator setter, angular velocity sensor and rudder position sensor are connected respectively to first, second, third and fourth inputs of summing-up amplifier model; outputs of failure indicator sensor, angular velocity sensor and ballast tank outlet valve are connected respectively to first, second and third inputs of fast-time ship model whose fourth input is connected with first output of program unit model whose second output is connected with inlet valve of ballast tank model.

EFFECT: enhanced stabilization of ship in trim angle by means of diagnosis system.
