FIELD: processes.
SUBSTANCE: invention relates to the control and diagnostics of automatic control systems and their components. It is achieved by pre-recorded response known good system, define the outputs models obtained from the use of parametric sensitivity function, which in turn connect coupling two models: the input of the first model is supplied test signal output of the first model becomes the input unit to the desired parameter , connect the output of the first model to the input of the second through the transfer function, input of the second pattern becomes the output of the controlled parameter, remove the output signals after each block of the second model, the output signals recorded, replace the system with nominal controlled, the system input is fed the same test signal determine the signal-controlled system determines the deviation signals of the controlled system from the nominal values determine diagnostic features, the minimum value of the diagnostic characteristics are determined by the faulty parameter.
EFFECT: reduction in computational costs associated with the implementation models with test parameter deviations.
