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.

Motion control device and motion control method for ship

A system for warning against forgetting to pull out an information recording medium can improve working efficiency upon mounting a navigation unit and an on-board radio unit onto a vehicle, and notify a user of an alarm that causes no uncomfortable feeling, and is still inexpensive to manufacture. A drive unit switch detects when a control part is turned off, also detects, through a communication line, a residual state of an IC card with respect to an on-board device, and notifies the result of the detection to a the voice generation part. When the IC card is 'absent' in the on-board device, the control part interrupts the supply of power to the on-board device through the on-board device power supply line.
