FIELD: measurement technology.

SUBSTANCE: invention relates to the field of monitoring and diagnosing of automatic control systems and their components. Pre-recorded reactions known good discrete time system diagnostics for discrete cycles with discrete constant pitch on the observation interval at the control points, and define the integral estimates of the output signals of a discrete system. To do this at the time of the test signal to the input of a discrete system with nominal started simultaneously discrete integration outputs of the control system in each of the control points with discrete weights by applying a first input of the multiplication of output signals the control system to a second input of the multiplication is fed discrete exponential signal outputs of the multiplication is fed to the input of a discrete integration. Discrete integration is completed in the time obtained by integrating the evaluation of output signals is recorded, record the number of pending single defect blocks, define the integral estimates outputs models for each of the control points and each of the positions of the input signal obtained by changing the position of the input signal after each of the blocks. For this in turn for each block of discrete dynamic systems move feed location of the input signal at the output of each unit is fed through the adder input signal and are discrete integral evaluation of output signals of the system for a test signal derived from the discrete integration evaluation of output signals for each of the control points and each of the models with different positions of the input signal is recorded, determine the deformation of the integral output signals estimates discrete model obtained by moving the position of the input signal at the position after each of the respective blocks. Determine the normalized values of integral deformities estimates discrete model of the output signals obtained by moving the position of the input signal at the position after every respective blocks, a system is substituted with nominal controlled. Input to the system is fed the same test signal. Determine the integral estimates of the output signals of the controlled system for discrete control points. Determine strain integral estimates of output signals controlled by discrete systems for the control points from the nominal values. Determine the value of the normalized strain integral estimates of output signals controlled by the discrete system. Determine diagnostic features, the minimum value of the diagnostic characteristics are determined by the serial number of the defective block.

EFFECT: technical result is the ability of the method to find defects in a discrete dynamical system with arbitrary connection blocks.
