METHOD OF SEARCHING FOR FAULTY MODULE IN DYNAMIC SYSTEM Russian patent published in 2012 - IPC G05B23/02 G06F11/22 

FIELD: information technology.

SUBSTANCE: number of dynamic modules of a controlled system is determined, the reaction of a good system is recorded at an interval at control points and integral estimates of output signals of the system are determined. System signals are transmitted to the first inputs of multiplier units; an arithmetic mean value of moduli of signal time derivatives is transmitted to second inputs of the multiplier units; output signals of the multiplier units are transmitted to inputs of integration units; integration is completed at a certain moment in time; output signal estimates obtained from integration are recorded; simultaneously, integral estimates of signals of models are determined for each of the control points, obtained as a result of test deviations of parameters of each of the modules, for which a corresponding test deviation of parameters is introduced into each model for the dynamic system module. Deviations of integral estimates of signals of the model, obtained as a result of test deviations of parameters of corresponding modules, are determined. Standardised values of deviations of integral estimates of signals of the model are determined. Standardised values of deviations of integral estimates of signals are determined. Diagnostic features are determined and a faulty module is determined from the minimum value of the diagnostic feature.

EFFECT: increased noise-immunity of diagnosing continuous automatic control systems.
