Continuous performance analysis system and method
First Claim
1. A method of conducting a continuous performance analysis for a system, comprising the steps of:
- collecting transient performance data for a first parameter of the system and a second parameter of the system using a first sensor and a second sensor, respectively;
supplying the transient performance data to a processor; and
applying transfer functions to the transient performance data for at least one of the first and second parameters, in the processor, to thereby generate phase compensated performance data representative of a steady state relationship between the first and second parameters; and
for each phase compensated performance datum, calculating, in the processor, an estimate of the first parameter at a predetermined value of the second parameter using the phase compensated performance datum and a previously stored performance characteristic curve representative of the steady state relationship between the first and second parameters.

Abstract
A system and method of conducting a continuous performance analysis for a system includes collecting transient performance data for a first parameter of the system and a second parameter of the system. Transfer functions are applied to the transient performance data for at least one of the first and second parameters to thereby generate phase compensated performance data representative of a steady state relationship between the first and second parameter. For each phase compensated performance datum, an estimate of the first parameter is calculated at a predetermined value of the second parameter using the phase compensated performance datum and a previously stored performance characteristic curve representative of the steady state relationship between the first and second parameters in a deterioration model extrapolation method. A very efficient binning method is used for storing phase compensated performance data and converting them into steady state performance characteristic curves of any non-linear shape.
