METHOD OF FINDING FAULTY UNITS IN DISCRETE DYNAMIC SYSTEM Russian patent published in 2013 - IPC G05B23/00 

FIELD: information technology.

SUBSTANCE: reaction of a good, time-discrete system is recorded first; integral estimates of output signals of the discrete system are determined; the number of analysed single and multiple defects of units is recorded; integral estimates of signals of the model for each control point are determined; deviations of integral estimates of signals of the discrete model are determined; standardised values of deviations of integral estimates of signals of the discrete model are determined; the system with nominal characteristics is replaced with the controlled system; an analogue test signal is transmitted to the input of the system; integral estimates of signals of the controlled discrete signals are determined for control points for the discrete integral transformation parameter; deviations of the integral estimates of signals of the controlled discrete system are determined for control points from the nominal values; standardised values of deviations of integral estimates of signals of the controlled discrete system are determined from the ratio; diagnostic features are determined from the ratio; the index number of the single defect of the unit or a combination of defects of units is determined from the maximum value of the diagnostic feature.

EFFECT: broader functional capabilities of the method of finding one or several faulty units at once in a dynamic system with arbitrary connection thereof, and lower computational costs associated with use of a simpler diagnostic feature.
