FIELD: test technology.
SUBSTANCE: invention relates to the diagnosis of automatic control systems. In the method of troubleshooting in a continuous dynamic system, based on the introduction of trial deviations, faults are detected, the monitoring time and the signal conversion parameter are determined. Integral estimates of signals are used as dynamic characteristics. Control points of the system are determined, the reaction of the object of diagnosis and a known good system is recorded and the estimates of the signals of the known good system are determined. As a trial deviation, the total number of combinations of structural and topological faults is considered. Output of the model for each control point is estimated. State of each combination of structural blocks of the dynamic system is changed. Deformation of the estimates of the signals of the mode is determined and recorded. Normalized strain values of the model signal are estimated and the diagnostic features are determined. Minimum of the diagnostic sign is determined by the combination of a multiple structural and topological defect.
EFFECT: functionality of the method is extended.
