Abstract
Proper setting of feedback control according to the ship. The ship control device includes processing circuitry configured to set the ship characteristic parameters of the combined system of first order lag and dead time, which integrates the behavior of the rudder and the behavior of the ship. Using the ship characteristic parameters, the processing circuitry is further configured to calculate the control parameters of feedback control with respect to the rudder angle of the rudder. Using the control parameters, the processing circuitry is further configured to perform feedback control.
