Diagnostic Models of Sensitivity of Automatic Control Systems

An approach to the construction of a simplified diagnostic model for analyzing the distinguishability of single block defects in continuous dynamic objects, based on a sensitivity model using integral signal transformations, is considered. The influence of the parameter of the integral transformation of the signals of the object of diagnosis on the a priori and actual distinguishability of single defects is studied. A good agreement between the values of a priori and actual distinguishability of single defects was found when using a single stepwise input action on the object. All experiments and simulations were carried out using specialized software complex created in Scilab/SciNotes.
