Abstract
A ship speed control device is provided, which includes a calculator and a throttle command value setter. The calculator calculates a throttle calculation value based on a difference between an actual ship speed and a target ship speed. The throttle command value setter sets, when the actual ship speed is below a first threshold determined based on a given throttle upper limit and the throttle calculation value is at or above the throttle upper limit, a throttle command value to the throttle upper limit.
Claims20
An AP controller, comprising:
- processing circuitry configured
- to calculate a throttle calculation value based on a difference between an actual ship speed and a target ship speed;
- and
- to set a throttle command value to the throttle upper limit when the actual ship speed is below a first threshold determined based on a given throttle upper limit and the throttle calculation value is at or above the throttle upper limit.
A method of controlling a ship speed, comprising:
- calculating, by processing circuitry, a throttle calculation value based on a difference between an actual ship speed and a target ship speed;
- and
- setting, by the processing circuitry, a throttle command value to the throttle upper limit when the actual ship speed is below a first threshold determined based on a given throttle upper limit and the throttle calculation value is at or above the throttle upper limit.
A non-transitory computer-readable recording medium storing a program causing a processor of a ship speed control device to execute processing, the processor configured to control operation of the ship speed control device, the processing comprising:
- calculating a throttle calculation value based on a difference between an actual ship speed and a target ship speed;
- and
- setting a throttle command value to the throttle upper limit when the actual ship speed is below a first threshold determined based on a given throttle upper limit and the throttle calculation value is at or above the throttle upper limit.
