Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Functional diagnosis of bilinear objects in steady-state mode Tsygankov M.P., Boikov S.Yu. The peculiarities of functional diagnosis of bilinear objects in steady-state mode are considered in the article. The features of displaying the object’s defects in the characteristics of discrepancy in control equations of diagnostic model are identified. The diagnostic algorithm invariance relatively to changes in a technological regime is shown.
