Instruments and Systems: Monitoring, Control, and Diagnostics Annotation << Back Evaluation of Stability of Nonlinear Objects in Predictive Models of Production Systems YU.S. SHEVNINA, E.I. MINAKOV, D.A. MAKARICHEV The article presents approaches to assessing the stability of nonlinear objects in predictive models of microelectronics production systems taking into account a random structure. The article considers the equivalent stability in the mean square of continuous systems, bilinear systems, and discrete systems with a random structure used in the production of microelectronics products. Examples of predictive models of production systems and an assessment of the stability of nonlinear objects based on the proposed approaches are given. The criteria for the stability of nonlinear objects in predictive models are formulated. The issues of adapting the assessment of the stability of nonlinear objects to the features of a specific class of production systems are considered. Keywords: predictive models, production systems, nonlinear objects, equivalent sta-bility in mean square, systems with random structure. DOI: 10.25791/pribor.11.2025.1630 Pp. 36-42.
