METHOD FOR CALCULATING CONFIDENCE ON PREDICTION IN FAULT DIAGNOSIS SYSTEMS
First Claim
Patent Images
1. A fault diagnosis system comprising:
- a fault detection system for taking in a plurality of sensor readings from a gas turbine engine;
said plurality of sensors providing readings to a fault isolation system, and to a network communicating with a database of prior predictions, and the database associating the prior predictions with a confidence level; and
said fault isolation system providing a predicted fault to an output, and a confidence level in the predicted output also being provided to the output.

Abstract
A method and system is developed that provides a confidence measure of a prediction of a fault in a gas turbine engine. The confidence measure is developed based upon evaluating the results of a plurality of past predictions and comparing them to an actual fault.
