control system

The synthesis of the structure of the automatic control system of direct current motors is carried out, and the methodology of the study of the duration of the transient process during the control of the direct current motor is presented. A study of the influence of the regulator parameters on the duration of the transition process was carried out, which allowed to choose the optimal ones for the criterion of the minimum duration of the transition process

The article presents modern schemes for the organization of wind-solar power supply systems. Available approaches to managing the energy-dynamic process of operation of wind power plants as part of hybrid power supply systems are given, and modern research on this topic is given. The results of the development of a mathematical model of the energy-dynamic processes of the hybrid wind-solar power supply system, which includes wind power plants, solar panels, and a battery energy storage system. The universal structural diagram of such a system is substantiated.

The article develops a method of controlling a group of unmanned aerial vehicles to search for and destroy enemy objects.  The method is to recognize situations and adjust the actions of the group according to it.  The basis of the method is the use of an intelligent decision support system.  It provides situation recognition, using image recognition materials (intelligence materials), generalization of the obtained information and its comparison with the elements of the set of descriptions of typical situations.  The method of controlling a group of unmanned aerial vehicles to search for a

The article is shown the possibility and efficiency of the using of the ATV320 frequency inverter as an automation tool in case using of integrated logic controller ATV Logic. The example of practical realization of the control system of crusher electric drive is given.

The control system of electric drives with Crankshaft mechanism load has been analyzed. Method of tuning speed feedback adjusting was developed. The result can be used for the designing new systems of electric drives.

The sucker-rod oil pumping unit productivity is influenced by lots of factors, including the operation mode of the jack pump electric drive system. Settings of the electric drive system affect the system’s energy indicators, overhaul period and oil production volume. Therefore, an effective operation of oil production units is an important factor influencing the cost of the produced oil. The paper proposes a method of selecting the speed of the driving motor of the jack pump electric drive that allows balancing the sucker-rod oil pumping unit productivity and the reservoir flow rate.

The method of measurement and evaluation of electrical parameters a larg antenna systems for ultra-high frequency bands is developed, that were not provided for the use of such antennas by their design. For ensure the necessary radio parameters in professional antenna systems (AS) use parabolic antenna reflectors with large diameters of 5 to 12 meters or more. The creation of such antennas require large expenditures for their production and metrological support by parameters setting.

Forming of network organizationally-productive structure which embraces the row of
subdivisions of interrelated enterprises and general process of production from supply of
components to the final products is considered in the article. For the territorial forming of
organizationally-productive structures a characteristic transition is to network organization of
business processes, which brightly shows up in activity multinational corporations. Expansion
of organizational and atomistic organizations accompanied by minimization of mutual
