Compensating for temperature effects in a health monitoring system

摘要

A method is present for monitoring a structure. A plurality of modes is identified for a first response for the structure at a first temperature. Each mode in the plurality of modes is adjusted from the first temperature to the second temperature to form a plurality of temperature adjusted modes. A temperature adjusted response is formed from the plurality of temperature adjusted modes in which the temperature adjusted response is adjusted to a second temperature from the first temperature. The temperature adjusted response is compared to a second response to evaluate the changes in the structure between the two sets of measurements.
