Balyuta S. Synthesis of automated control systems of two level controls of rolling mill technological processes

A research object - there are processes in the systems of the automated control by the technological parameters of the systems of the automated control the technological processes of the rolling mils. A research aim is a ground and development of perspective conception of synthesis of the systems of the automated control by the technological processes of rolling mils on the basis of the improved mathematical models of rolling mils and developed methods of two-level optimal control. Research meth-ods and apparatus are fundamental positions of automatic control theory, state space methods , filtration theory methods, flow-age theory methods, rolling methods, geometrical methods of analysis and synthesis of control system on the basis of tensor-group approach and continuous groups of transformations of Lee algebra. Theoretical results - the method of synthesis of the systems of the automated control is first offered by the technological processes of flatting mills on the basis of conception of two-level optimal control and decision of intricate problem of synthesis of the multidimensional system of high order on a decision at bottom level of row of subtask of synthesis of regulators of local subsystems of control by the mechanisms of separate cages of rolling mils l and decision at top level of task of synthesis of control local subsystems with the purpose of optimization of global criterion. The practical value of performances consists in creation and practical realization of method of two-tier optimal synthesis of regulators of control system the geometrical parameters of the rolled stripe. The novelty of work consists in development and ground of perspective conception of synthesis of the automated control the technological processes of rolling on the basis of development and generalization of mathematical models and development of methods of two-level control the technological parameters of rolling. A degree of introduction is results, got at implementation of dissertation work, inculcated in the scientifik-production corporation "The Kyiv institute of automation", on "Chernihiv car factory", on "Chernihiv chemical fibre on Chernihiv water channel. Sphere of the use - in practice of creation of modern new and modernization of existent high-accuracy control system for upgrading of technological processes of rental production and for planning of modern and modernization of operating rolling mils, and also at creation of high-accuracy control system.
