Methodology for improving the efficiency of paper production at the production facilities of ukrainian enterprises

This paper highlights the current state of paper production in the current state of energy supply in Ukraine. Paper and cardboard production is an energy-intensive process. The author presents ways to solve the problem of backup power and steam supply to the enterprises, as well as shows the complexity of electronic control, regulation of the web tension between electric drives with the possibility of their precise correction and movement from drive to drive, their dependence on high-quality and reliable power supply.

Grounds for Searching the Best Solution for Controlling the Pressurized Water Reactor in Dynamic Modes when Changing the Controlled Parameters

The article focused on the development of information technology for the optimization of control over complex dynamic systems at the stage of their design that should realize possibilities of modeling of linear and nonlinear dynamic systems, the analysis and synthesis of such systems, their optimization on various quality criteria. The purpose of this article is to develop the structure and elements of information technology to optimize the control of complex dynamic systems, including automated control systems.

Features of dynamics controlled electromagnetic vibratory drive units for sealing concrete

The influence of the reaction of concrete mixture during its vibratory compaction on the dynamics of vibration unit with an electromagnetic drive, which is operated in the near-resonant mode, is researched. The dynamic model, which allows calculating the transients in multi-mass vibration devices with a controlled electromagnetic drive and which allows to choose the structure and the parameters of automatic control system regulators, is developed.
