An algorithm for searching for single parametric defects in continuous automatic control systems based on configurable dynamic models built on Laguerre filters in canonical form was considered. Numerical experiments were carried out to configure the diagnostic model. A set of vectors of reference defect technical states of the diagnostic object was calculated. On the basis of the calculated diagnostic features, the diagnostics of the introduced defects was carried out. The accuracy of the proposed algorithm and the diagnostic possibilities of applying the filters under consideration are estimated. For modeling and conducting numerical experiments, a special software package developed in Scilab / Xcos was used.
