Abstract
A system for monitoring operation of a gas turbine engine comprises a plurality of expert networks each configured to generate a separate gas path parameter responsive to a separate actuator position. A router network configured to generate a weighting vector responsive to at least one ambient condition parameter. The weighting vector includes a plurality of weighting values each associated with one of the plurality of expert networks. Summing circuitry configured to apply the plurality of weighting values to each of the associated separate gas path parameters from the plurality of expert networks and sum each of the plurality of weighted separate gas path parameters from the plurality of expert networks to a weighted sum value.

A system for monitoring operation of a gas turbine engine, comprising:
- a plurality of expert networks each configured to generate a separate gas path parameter responsive to a separate actuator position;
- a router network configured to generate a weighting vector responsive to at least one ambient condition parameter, wherein the weighting vector includes a plurality of weighting values each associated with one of the plurality of expert networks;
- and
- summing circuitry configured to apply the plurality of weighting values to each of the associated separate gas path parameters from the plurality of expert networks and sum each weighted separate gas path parameter from the plurality of expert networks to a weighted sum value.
A method for monitoring operation of a gas turbine engine, comprising:
- generating a separate gas path parameter responsive to a separate actuator position using a plurality of expert networks;
- generating a weighting vector including a plurality of weighting values each associated with one of the plurality of expert networks responsive to at least one ambient condition parameter using a router network;
- applying the plurality of weighting values to each of the associated separate gas path parameters from the plurality of expert networks using summing circuitry;
- and
- summing each weighted separate gas path parameter from the plurality of expert networks using the summing circuitry to generate a weighted sum value.
A system for monitoring operation of a gas turbine engine, comprising:
- a plurality of expert networks each configured to generate a separate gas path parameter responsive to a separate actuator position, wherein the plurality of expert networks each comprises a first neural network configured to optimize operation of the gas turbine engine;
- a router network configured to generate a weighting vector responsive to at least one ambient condition parameter, wherein the router network further comprises a plurality of second neural networks configured to optimize operation of the gas turbine engine, wherein the weighting vector includes a plurality of weighting values each associated with one of the plurality of expert networks;
- a lookup table configured to output a separate gas path parameter responsive to the separate actuator position, wherein the lookup table further comprises a plurality of gas path parameters each associated with a particular separate actuator position;
- and
- summing circuitry configured to apply the plurality of weighting values to each of the associated separate gas path parameters from the plurality of expert networks and the lookup table and sum each weighted separate gas path parameter from the plurality of expert networks to generate a weighted sum value.
