Shevchuk O. Models of information technology of processes of combination of paints in roller printing machines

The dissertation is devoted to the decision of an actual scientific problem of development of models of information technology of system of control and management of combination of paints of rolled printing machines on the basis of creation of information models of multipolar components for research, calculation and improvement of elements and systems of rolled printing machines of arbitrary structure. It is shown that currently there are no models of color matching in absolute coordinates and dynamic processes of color matching. New approaches to the description of electromechanical systems based on creation of multipolar information models of components of electromechanical and tape systems are developed. The electromechanical and tape system of the printing machine is presented in the form of six-pole information models of components and connections between them. The properties of the paper tape section as a viscoelastic system under the action of external constant and variable load have been studied. The basic relation describing the properties of a tape-conducting system with a viscoelastic tape in a steady state is obtained. The influence of the phenomenon of creep and transient characteristics of tension, in particular newsprint and magazine paper are investigated. Optimization of the tension system with the use of PID regulator allowed to reduce the disturbance by 2.5 times. The expediency of dividing the control area into an active dynamic and stationary fixed part, which is respectively provided by PI and PD regulators, is indicated. The corresponding block diagram of the digital regulator of combination of paints is offered.
