This paper presents an overview of modern adaptive control systems for vehicle. It shows simulation results of vehicle flight with using the adaptation algorithm for position-control system, with estimation loop of additional disturbances, and with the reference mathematical model and astatism. The simulation results for two cases (for given constant coefficients of adapting and using the automatic settings adjustment coefficients) are presented.

In the article the question of the distribution of the load factor of a synchronous generator, which determines the percentage of the PTO on the particular consumer generator. When transporting the electricity consumers on several lines from different energy sources, there is a problem of rational distribution of power level that the consumer will take from each of the sources. This paper proposes a method of allocation, which aims to minimize power losses in power lines. Disabled distribution law SG load factor, which takes into account line losses and possible limitations on the level of generated power generators.

Recently becoming urgent problem of managing distributed processes of production, transmission and consumption of energy. This fact is associated with the emergence of a significant number of generators and the possibility of a primary control on all elements of the grid. In this connection, in proposed three-level distributed power grid management, which includes the upper level of segmentation networks, distributed control average frequency and power level and a lower primary control. The methods of control for each of the above levels, the results of simulation.

Keywords: smart grid management system, distributed control, frequency control and power.

In the paper we consider the energy efficiency of electric trains in overcoming the curved portion of the profile path. In this paper, were synthesized motion control algorithms that will help conserve energy resources by means of changes in traffic patterns electric depending on the profile path. The simulation electrorolling stock motion by offer the model showed a reduction in energy consumption compared to the nominal operation.

The simulation of two-dimensional spherical crystals consisting of a large number of particles is carried out. These shells were analyzed based on their geometric structure and energy distribution. Various types of defects formed in a state of equilibrium  is considered. Being shown the ambiguity of the existing method of their interpretation. A new way of describing such defects in the close-packed two-dimensional crystals with different topology is suggested.  

Keywords: topological defects, two-dimensional materials, spherical crystals, topological charge

This paper presents key capital structure determinants of construction companies and their impact on fund raising and financing mix formation in accordance with the conditions of construction activity. It was found that profitability and tangibility have a positive effect on leverage, risk - the negative and the effect of company size, assets growth rate and taxes is ambiguous.
