GOVERNOR CONTROL DEVICE AND CONTROL METHOD

摘要

PROBLEM TO BE SOLVED: To improve fuel consumption by performing precise governor control by taking into consideration a turbo-lag, in an engine having a turbocharger.SOLUTION: An actual rotating speed of a main machine 13 for a ship having the turbocharger 13T is detected in an actual rotating speed detecting block 14, and a deviation of the actual rotating speed set as a rotating speed command is input to a PID arithmetic operation part 15. Output of the PID arithmetic operation part 15 and output of a PID control regulating part 17 are input to a switch 16, and one output is output to a fuel supply device 18 as a governor command. Switching of the switch 16 is controlled by a comparing part 19 for comparing the rotting speed command with the actual rotating speed, and when increasing a load and when accelerating, the output of the PID control regulating part 17 is set as the governor command over a turbo-lag period. The PID control regulating part 17 increases a present governor command 1% by 1% over the turbo-lag period.
