    Optimization of electricity costs in residential heat supply systems
    (КПІ ім. Ігоря Сікорського, 2024) Stenin, A.; Pasko, V.; Soldatova, M.; Drozdovich, I.
    Currently, there is a large number of objects related to recirculation of material flows, mixing of reagents of liquid and gaseous media, etc. Among them are heat supply systems of residential buildings. Their dynamics are described by differential equations with a deviating argument. Optimizing the operation of such objects using known methods is quite difficult. This paper proposes a dummy variable method for reducing the original system of differential equations with a deviating argument to a system of ordinary differential equations and transfer equations for which known optimization methods can be applied. The method is generalized to systems with a non-stationary deviating argument and to systems with several processes having an aftereffect. The practical use of the dummy variable method is shown on the example of solving the problem of optimal control of the heat exchange process in a private residential building.

    Synergetic synthesis of optimal control laws of nonlinear dynamic objects
    (КПІ ім. Ігоря Сікорського, 2023) Stenin, A.; Pasko, V.; Soldatova, M.; Drozdovich, I.; Stenin, S.
    The synergetic synthesis of optimal stabilizing control laws for one class of nonlinear dynamic objects proposed in the article is based on the joint use of the well-known ACOR method and a specially designed synergetic functional. Synergetic synthesis of optimal stabilizing control laws based on the ACOR method and a specially designed synergetic functional that meets the conditions formulated in the article allows, on the one hand, to ensure asymptotic stability and, on the other hand, to ensure the specified dynamic properties of transient processes for one class of nonlinear dynamic systems. The practical implementation of this approach is demonstrated using the example of the synergetic synthesis of the law of optimal stabilization given in the article.
