# Automated analysis of non-stationary machine performance

## Abstract

A method for monitoring at least one machine including causing at least a first sensor to acquire at least a first non-stationary signal from at least one machine operating in a non-stationary manner during at least one operational time frame, the first sensor(s) providing at least a first non-stationary output, causing at least a second sensor to acquire at least a second non-stationary signal from the machine(s) during the operational time frame(s), the second sensor(s) providing at least a second non-stationary output, fusing the first non-stationary output(s) with the second non-stationary output(s) to produce a fused output, extracting at least one feature from the first and/or second non-stationary signal(s) based on the fused output, analyzing the feature(s) to ascertain a state of health of the machine(s) and performing a repair operation, maintenance operation and/or modification of operating parameters of the machine(s) based on the analyzed state of health.
