Abstract:
To provide a motion control device for a ship, which does not require adjustment of weights of an performance function, and is less liable to fail in control calculation by building optimization calculation only into a part of classical feedback control, the motion control device, which is configured to cause a ship, on which a plurality of outboard engines are installed, to cruise along a desired trajectory, includes: a trajectory generator configured to output a trajectory command; a controller configured to output a control force command based on the trajectory command and a sensor information group output from a sensor group provided for the ship; and a control force distributor configured to carry out, based on the control force command, optimization calculation for operation amounts required for the plurality of outboard engines in accordance with a constraint condition set in advance so as to output the operation amounts.

Claim (Index 3):
The motion control device for a ship according to  claim 2 , wherein:\n the plurality of outboard engines comprise a first outboard engine and a second outboard engine; and the distribution calculator is configured to calculate, as the driving force signal, a solution F* for minimizing an performance function J in a normal form given by the following expression under at least one linear inequality constraint condition: J = 1 2 \ue89e F T \ue89e RF - f T \ue89e CF C \u2261 [ 1 0 1 0 0 1 0 1 L y - L x - L y - L x ] f = [ X f Y f N f ] F = [ f X \ue89e \ue89e 1 f X \ue89e \ue89e 1 f X \ue89e \ue89e 2 f Y \ue89e \ue89e 2 ] where, in a body-fixed coordinate system,\n X f  represents an X-axis direction translational force command, \n Y f  represents a Y-axis direction translational force command, \n N f  represents a Z-axis direction rotation torque command, \n f X1  represents a propulsion force operation amount in an X-axis direction directed to the first outboard engine, \n f Y1  represents a propulsion force operation amount in a Y-axis direction directed to the first outboard engine, \n f X2  represents a propulsion force operation amount in the X-axis direction directed to the second outboard engine, \n f Y2  represents a propulsion force operation amount in the Y-axis direction directed to the second outboard engine, \n R represents a positive semi-definite matrix, and \n L x  and L y  represent distances in the X-axis direction and the Y-axis direction, respectively, from a center of gravity of the ship to a rotation center of each of the first outboard engine and the second outboard engine.
