GAS TURBINE ENGINE OPTIMIZATION CONTROL DEVICE

摘要

A gas turbine engine optimization control device estimates a specific fuel consumption using a given control parameter of a variable mechanism, determines a change between a specific fuel consumption estimation value by the control parameter of the variable mechanism in a previous operation period and a specific fuel consumption estimation value by the control parameter of the variable mechanism in this operation period, determines a new control parameter of the variable mechanism with which the specific fuel consumption estimation value approaches a minimum, adds the new control parameter of the variable mechanism to a preset control parameter initial value, and sets the addition value to be a control parameter command value of the variable mechanism in a next operation period.

1. A gas turbine engine optimization control device comprising:
a specific fuel consumption estimation operation section that estimates a specific fuel consumption using a sensor feedback value of a control parameter of a variable mechanism given for each predetermined operation period; a control parameter reoperation section that determines a change between a specific fuel consumption estimation value based on a sensor feedback value of the control parameter of the variable mechanism in a previous operation period and a specific fuel consumption estimation value based on a sensor feedback value of the control parameter of the variable mechanism in this operation period, and determines a new control parameter command value of the variable mechanism with which the specific fuel consumption estimation value approaches a minimum; and a control parameter command value operation section that adds the new control parameter command value of the variable mechanism determined by the control parameter reoperation section to a preset control parameter initial value of the variable mechanism, and outputs the value as a control parameter command value of the variable mechanism in a next operation period.
