    The optimal control problem for output material flow on conveyor belt with input accumulating bunker
    (Южно-Уральский государственный университет, 2019) Pihnastyi, O. M.; Khodusov, V. D.
    The article is devoted to the synthesis of optimal control of the conveyor belt with the accumulating input bunker. Much attention is given to the model of the conveyor belt with a constant speed of the belt. Simulation of the conveyor belt is carried out in the one-moment approximation using partial differential equations. The conveyor belt is represented as a distributed system. The used PDE-model of the conveyor belt allows determining the state of the flow parameters for a given technological position as a function of time. We consider the optimal control problem for flow parameters of the conveyor belt. The problem consists in ensuring the minimum deviation of the output material flow from a given target amount. The control is carried out by the material flow amount, which comes from the accumulating bunker into the conveyor belt input. In the synthesis of optimal control, we take into account the limitations on the size of the accumulating bunker, as well as on both max and min amounts of control. We construct optimal control of the material flow amount coming from the accumulating bunker. Also, we determine the conditions to switch control modes and estimate time period between the moments of the switching.

    Optimal Control of the Parameters of the Production Line
    (ARC Publications, 2019) Pihnastyi, O. M.
    The problem of optimal control of the parameters of the production flow line – stocks (work in process) and the rate of processing of objects of labour for a technological operation is considered. The article presents a mathematical formulation of the problem of controlling the parameters of a production line with restrictions on work in progress and the speed of machining parts for each technological operation. The control program is determined by the specified quality criteria. An example of the calculation of the optimal control for the production line parameters is presented.

    Optimal Control Problem for a Conveyor-Type Production Line
    (Springer Science+Business Media, 2018) Pihnastyi, O. M.; Khodusov, V. D.
    A method for constructing optimal control of the conveyor-type flow line parameters is developed. The model of the conveyor line is represented by the partial differential equation, which allows to take into account the distribution of products along the technological route as a function of time. Various variants of stepped speed control of the conveyor belt are investigated. The features of step control are determined. The divergence the rate of output by the flow line from the given demand for different parameters of step control is shown.
