Defect Search Using the Input Signal Position Change And the Binary Diagnostic Sign1

Abstract

Article deals with research problem of an algorithm for single defect search in a continuous dynamic system of an automatic control class with depth up to a dynamic block is considered on the basis of a position change of the input signal based on integral estimates of signal deviations of model and object using a binary diagnostic sign for the presence of a defect. This approach simplifies the implementation of the algorithm, especially in the diagnosis of non-linear objects. The use of position change of the input signal can reduce the hardware or software costs associated with the implementation of sensitivity functions or trial deviations of model parameters and simplicity of the algorithm calculating the normalized diagnostic sign. The results of the implementation of the algorithm, showing its effectiveness and to ensure high distinction of the defects.
