Process modeling in automation systems

Koshevoy V.O., Lavrikova A.G., Leonova E.S., Porokhnyak O.B., Guter V.V.  Modeling cyber-physical states of FCC unit

State modeling presumes the selection of isolated data blocks from the total plant information. The paper shows the applicability of the “state” concept to an oil refining unit. It demonstrates the mathematical state selection techniques and proposes the new stable state concept. The possibility of selected states interpretation through the product qualities is demonstrated.

Keywords: clustering, process unit operation states, quality estimators, state graph, state stability.

Kilin G.A., Suslov A.I., Kavalerov B.V., Gribkov I.N., Pleshivyh A.S.  Neural modeling in semi-full-scale testing of automated control systems in propulsion engineering

The paper examines the possibility for connectionist model integration into a semi-full-scale testing complex for automated control systems in propulsion engineering. The outlook for and the advantages of using connectionist models in model-oriented design technology are discussed. With the example of gas-turbine power plants, the foundation architecture of a neural network is presented that significantly simplifies the search of neuron network architecture parameters and the development connectionist model.

Keywords: artificial neural networks, mathematical model, testing, test bench, model-oriented design, gas-turbine power plant, software suite.

Puzanov A.V.  Simulation-based investigation of thermal conditions of control block of mobile equipment drives

Russian geopolitical interests in the Arctic Zone require high operability of mobile equipment, its modules and components in low temperatures. Engine start in the frost is a difficult technical process. The paper offers a solution to the problem of drive control block heating to the operating temperature range in minimum time and with the lowest temperature gradient to exclude thermal deformation.

Keywords: drive control system, thermal operating conditions, heating simulation.
