Abstract
A method and apparatus for distributing control of multiple engines amongst the engines in a power generation system that has a central controller, comprises the steps of: receiving aboard each engine from the central controller a control signal representative of a desired fuel flow; metering fuel at a fuel metering point aboard each engine; sensing at least one parameter aboard each engine proximate the fuel metering point that is representative of fuel flow; adjusting the fuel metering aboard each engine to cause the sensed parameter to correlate to the desired fuel flow; and transmitting a monitoring signal from each engine to the central controller that is representative of the adjusted fuel metering.

A method for distributing control of multiple engines amongst the engines in a power generation system that has a central controller, comprising the steps of:
- receiving aboard each engine from the central controller a control signal representative of a desired fuel flow;
- metering fuel at a fuel metering point aboard each engine;
- sensing at least one parameter aboard each engine proximate the fuel metering point that is representative of fuel flow;
- adjusting the fuel metering aboard each engine to cause the sensed parameter to correlate to the desired fuel flow;
- and
- transmitting a monitoring signal from each engine to the central controller that is representative of the adjusted fuel metering.
A distributed engine control system for distributing control of multiple engines amongst the engines in a power generation system, comprising:
- a central controller for transmitting a control signal representative of a desired fuel flow to each engine;
- a fuel control valve aboard each engine for metering fuel at a fuel metering point aboard each engine;
- at least one sensor aboard each engine for sensing at least one respective parameter aboard each engine proximate the fuel metering point that is representative of fuel flow;
- and
- a fuel valve controller aboard each engine for adjusting the fuel metering aboard each engine to cause the sensed parameter to correlate to the desired fuel flow and transmitting a monitoring signal from each engine to the central controller that is representative of the adjusted fuel metering.
