Description
In this article we have developed the optimum speed diagrams for small movements of electric drive’s actuating device. We have identified analytical dependences of position of automatic regulation of system control signal of time, which allows to form the optimum speed diagrams for small movements of electric drive’s actuating device with ultra-precision

01.00.00 Physical-mathematical sciences
DescriptionThe time-optimal diagram of movement of the executive body of the precision DC drive with elastic shafting with constrains of maximum current and the fifth derivative of the speed has been designed. The algorithm has been developed to determine the parameters of the time-optimal diagram of movement of the executive body of the precision DC drive with elastic shafting with constrains of maximum current and the fifth derivative of the speed. The region of existence of the time-optimal diagram of movement of the executive body of the precision DC drive with elastic shafting with constrains of maximum current and the fifth derivative of the speed has been set. According to the results of the numeral experiment, the dependences of the duration of the cycle of movement of the executive body of the drive from prescribed displacement (rotation angle) for different values of the fifth derivative of the speed have been plotted

OPTIMUM SPEED OF DIAGRAMS FOR CHANGES OF TEMPERATURE OF A PRODUCT IN THE DEVICE OF AIR COOLING
DescriptionThree diagrams are developed for the changes of temperature of a product in air cooling devices with restrictions of speed of the systems’ performing parts of electric drive and it’s various derivatives at dispersal and braking. Parameters of optimum diagrams of speed for the big changes of temperature of a product in devices of air cooling are defined

Description
We have considered hybrid nontraditional and renewable sources of energy in terms of optimizing their work based on the knowledge of technical and functional peculiarities of each. We used classification of clusters of nontraditional and renewable energy of sources, depending on the proportion of replacing power in energy consumption and on the type of nontraditional and renewable energy of sources. We examined a simulation model of the hybrid cluster using the structural diagram and performed statement of the problem by means of the full and multifactor experiment. We applied the method of analysis of non-stationary random process disturbing influences

OPTIMIZATION OF DIGITAL CONTROL SYSTEM OF THE PROCESS OF GRAIN DRYING
DescriptionThe article is a study of digital continuous system and optimization of digital control systems. It is shown that the standard in the synthesis of digital systems should provide a continuous system, so first we need to create the desired continuous system and then we could try to get the digital system closer to it

FEATURES OF TECHNOLOGY OF WINE SUCH AS PORT FROM PERSPECTIVE RED AND WHITE GRAPE
DescriptionFeatures of technology of port from perspective red grape of Negro, Podlesniy, 40 let Pobedy, Dostoyniy and white - Bianka and First-born Magaracha are investigated. The organoleptic characteristics of re-ceived ports is given. Positive influence is established and explained at en-tering in researched strong wine materials the autoly-sis of yeast processed by electromagnetic fields VLF or the MICROWAVE. Experimental results are shown and optimum parameters of a fermentation, thermal processing and conditions of entering of an autolysis of yeast, MICROWAVES - EXTRACTS are determined.
