Synthesis of algorithms for stabilization ofthe level of inter-operative backlogs of the production flow line
(Національний технічний університет "Харківський політехнічний інститут", 2020) Pihnastyi, O. M.; Khodusov, V. D.
The report discusses methods for constructing algorithms for optimal stabilization of the value of inter-operational backlogs of the production flow line.
The stabilization problem the flow parameters of the production line
(Національний університет "Одеська морська академія", 2020) Pihnastyi, O. M.; Khodusov, V. D.
The problem of designing a system for optimal control of random deviations of flow parameters of a production line from the planned value is considered. The PDE-model of the production line was used as a foundation for the development of an algorithm for optimal control of the parameters production line. The method of Lyapunov functions was used to construct a system of operational control of flow parameters of production lines. The problem of stabilization of the value flow parameters of the production line (the task of operational control of the flow production) is formulated. The equations for the production line parameters in small disturbances are obtained. To assess the technological resources of the production system, which spent on the formation of control actions, the integral of the production line quality was introduced, the minimum value of which corresponds to the rapid damping of the flow parameters disturbance. Taking into account the specified quality criterion, the Lyapunov function of the production line is determined. Control actions are found that ensure the asymptotic stability of a given planned state of the production line flow parameters for a steady and transient mode of operation.
The problem of operational control of the flow production
(Екологія, 2020) Pihnastyi, O. M.; Khodusov, V. D.
This paper considers a method for constructing optimal control of random deviations of flow parameters of a production line from the planned value, based on the method of Lyapunov functions. The problem of stabilization of the values of the flow parameters of the production line (the problem of operational control of the flow production) is formulated.
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.
Stochastic equation of the technological process
(Igor Sikorsky Kyiv Polytechnic Institute, 2018) Pihnastyi, O. M.; Khodusov, V. D.
This document presents the construction of a stochastic equation for the process of manufacturing products on a production line. We base our research on the synchronized production line. The minimum size of the inter-operational storage is determined, at which the continuous production is possible. The stochastic equation of the production process is written in canonical form. The definition of the diffusion coefficient for the time of processing of subjects of labour.
Calculation of the parameters of the composite conveyor line with a constant speed of movement of subjects of labour
(National Mining University, 2018) Pihnastyi, O. M.; Khodusov, V. D.
The development of analytical methods for calculating the parameters of a composite conveyor line using the models containing partial differential equations. To calculate the parameters of the conveyor line with a constant speed of movement of subjects of labour, the apparatus of mathematical physics is used. The solution is given in an analytic form that specifies the state parameters of the production line for a given technology's position as a function of time. The scientific novelty of the results is the improvement of PDE-models of production systems of a conveyor type. The method for calculating the parameters of conveyor production, consisting of two connecting conveyor lines with a constant speed of movement of subjects of labour is offered. The considered method of calculation of conveyor production can be extended in case of a system with an arbitrary number of connecting conveyor lines. The practical significance lies in the fact that the proposed method for calculating the parameters of conveyor production can be used to design control systems for conveyor production with an arbitrary number of conveyor lines. An essential advantage of this method is that each conveyor line is described by a single partial differential equation, the solution to which is obtained analytically. Such a representation makes it possible to use solutions for predicting the state parameters of a production line.
