FIELD: control systems.
SUBSTANCE: invention relates to the diagnosis of automatic control systems. In the method of searching for a faulty unit in a continuous dynamic system based on introducing trial deviations and analyzing transmission signs, recording the number of system units, determining a monitoring time and an integral signal conversion parameter. Number of control points of the system is recorded, the reaction of the object to be diagnosed and the reaction of the sound system at these points is recorded. Integer estimates of output signals of a sound system are determined. Signs of deviations of integral estimates of output signals of the monitored system for control points from nominal values are determined. Values of deviations of integral estimates of output signals of the monitored system are calculated. Signs of deviations of integral estimates of output signals of the model, obtained as a result of trial deviations of parameters of units are determined. Values of deviations of integral estimates of output signals of the model, obtained as a result of trial deviations of parameters of blocks, are determined. Signs of presence of faulty unit are calculated.
EFFECT: improved noise immunity of the method.
