Document Type and Number:
Japanese Patent JP2016023605
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a fuel flow controller capable of dealing with a change in flow characteristics of a valve.SOLUTION: A fuel flow controller comprises: a valve degree-of-opening adjustment unit calculating a degree of opening of a fuel flow regulating valve to correspond to a command value of a flow characteristic on the basis of a correspondence relation between the flow characteristic of the fuel flow regulating valve and the degree of opening of the fuel flow regulating valve, and a command value of the flow characteristic required for the fuel flow regulating valve in response to a fuel flow command value, and adjusting a degree of opening of the fuel flow regulating valve to the calculated degree of opening; a flow-characteristic calculation unit calculating a first flow characteristic of the fuel flow regulating valve on the basis of a state quantity of fuel flowing in a fuel system in which the fuel flow regulating valve is provided; and a correspondence-relation update unit updating the correspondence relation so that the calculated degree of opening corresponds to the first flow characteristic.SELECTED DRAWING: Figure 2
