Position-Binary and Spectral Indicators of Microchanges in the Technical States of Control Objects

摘要

It is shown that, at the early stage of the change in the technical state of an object, the measurement information is partially lost because of the dynamics of the changes in the characteristics of the signals at the output of the corresponding sensors. When the traditional technique is used, this can be found only if the process is pronounced; for this reason, sometimes it is impossible to prevent accidents that can have disastrous effects. The proposed techniques for determination of the estimates of the position-binary and spectral noise indicators reflect with high accuracy the beginning of any micro-change in the control objects with the use of excess-frequency analysis by extraction of additional information from both the desired signal and the noise.
