METHOD OF SEARCHING FOR FAULTY UNIT IN CONTINUOUS DYNAMIC SYSTEM BASED ON CHANGE OF POSITION OF INPUT SIGNAL Russian patent published in 2015 - IPC G05B23/02 

FIELD: radio engineering, communication.

SUBSTANCE: in addition to the existing method, the present method includes determining n signal integration parameters which are multiples of $$\frac{5}{{Т}_k};$$ determining integral estimates of system output signals and model output signals for each of k control points and n integration parameters, for which the method includes, successively for each unit of the dynamic system, moving the point of transmitting an input signal to the output of each unit, transmitting the input signal through an adder and finding integral estimates of the system output signals for n parameters αl and a test signal; determining deformation of the integral estimates of the model output signals; determining standardised deformation values of the integral estimates of the model output signals; for k control points of the controlled system and n integration parameters, determining integral estimates of output signals, deformation of integral estimates of output signals, standardised deformation values of integral estimates of output signals of the controlled system; determining diagnostic features, the minimum of which determines the faulty unit.

EFFECT: improved noise-immunity.
