Abstract
A ship speed control system includes: a ship speed deviation calculation module which calculates a ship speed deviation based on the difference between an actual ship speed and a ship speed target value; and an input gain adjustment module which adjusts a gain input to a throttle control function to a first gain value when the ship speed deviation is not less than a first threshold value, and adjusts the input gain to a second gain value which is larger than the first gain value and smaller than the initial gain value when the ship speed deviation is not less than the first threshold value and not less than the second threshold value.
