FIELD: technological processes.
SUBSTANCE: to search for a topological defect a certain number of possible faults are fixed, the monitoring time is determined in comparison with the transient process time, the integral conversion parameter is determined, the test signal and integral signal estimates are used, the number of control points of the system is fixed, the reaction of the diagnostic object and the reaction of a good system at control points are registered in a certain way, integral estimates of the functioning system output signals are determined, registered, the integral estimates of the model output signals are determined for each of the control points obtained in a certain way, the system with the nominal characteristics is replaced with the monitored system, the input of which is given a similar test signal, the integral estimates, their deviations and normalized values of the deviations are determined, the diagnostic features and the topological defect are determined to a diagnostic sign minimum in a certain way on the basis of trial deviations.
EFFECT: reduced noise immunity of the diagnostic method for continuous automatic control systems.
