Algorithm For Searching For Multiple Structural Defects In Automatic Control Systems Using Sensitivity Functions

An algorithm for searching for multiple block defects in continuous dynamic objects is considered, based on the use of a structural sensitivity model and integral transformations of the object's output signals. The structural sensitivity model was obtained using the structural-matrix representation of the automatic control system. The influence of the value of the parameter of the integral transformation of the signals of the object of diagnosis on the actual distinguishability of multiple defects is studied. A quantitative criterion for the distinguishability of block defects is proposed and dependences of the distinguishability of various defects on the parameter of the integral transformation of signals for a particular model of the diagnostic object for various input signals are obtained. Modeling and computational experiments were carried out using a specialized software package created in the Scilab/SciNotes environment.
