Abstract (English):
The algorithm of statistical diagnostics used for the detection of measurement faults critical for ACS of manufacturing equipment and power units has been considered. Noise interference and pulse jamming and also a shift, drift and sensitivity loss of a measuring channel belong to them. A preliminary synthesis of an algorithm was carried out in the structure of a self-contained complex having a simulator of measurement faults, and their final adjustment is carried out according to the results of semi-natural tests. The latter provides for the application of diagnostic algorithms to processing records of natural information.
