An inverse model ship power system that takes into account changes in the dynamics caused by the powerful work of electromechanical subsystems combined propulsive complex. The analysis of this model adaptive control system forms the vessel motion control strategy that takes into account limitations in dynamics, due to the influence of power converters on vehicles power system. © 2016 IEEE.

The effect of Ag2CO3 on the thermophysical properties of epoxy composites was investigated. The thermal linear expansion coefficient of materials that can be used in different temperature ranges has been established. The thermal stability and structural features of materials on increase in temperature were studied by the method of differential thermal analysis and thermogravimetrical analysis. The activation energy of developed polymer composites was calculated. Temperature ranges in which the structural transformations occur, namely, the deformation of epoxy binder macrochains and segments and breakdown of chemical bonds, were also identified by an infrared spectral analysis. © 2017 by Begell House, Inc.

The analysis of the operation of PID regulators is performed with both perfect differentiation and taking into account the real differentiation of the controlled variable s deviation. Compared the sensitivity of automatic control systems (ACP) with a PIDD2D3 controller tuned to a minimum of the integral criterion for the modulus and a minimum of the linear integral criterion with the same stability margin according to a given value of the oscillation frequency index. The possibility of a robust compromise adjustment that guarantees the preservation of a given margin of stability under the predicted nature of the change in the dynamics of an object is considered. © 2017 IEEE.

The results of studies of the effect of synthetic discontinuous fibers on physico-mechanical and tribological properties of epoxy composites. Analysis of the dependence of the temperature and the coefficient of friction of epoxy composites by fiber content and traveled friction way possible to establish optimum mass ratio of fillers in a material with high performance. In order to form a matrix with improved physicalmechanical and tribological properties of optimum content of the glass and polyacrylonitrile fibers is - q = 0,02 wt.%.

The influence of the MoS2 and Mg3Si4O10(OH)2 dispersed fillers and synthetic discrete fibers on the tribological properties of epoxy composites was investigated. An analysis of the curves for the dependence of the operating temperature and friction coefficient of epoxy composites on the fillers content and traversed friction path make it possible to reveal the optimal weight ratios of fillers in material with improved operating characteristics. The mechanism underlying the wear of epoxy composites has been substantiated. The process of formation of a lubricant film of significant thickness due to the synergistic interaction of disperse particles and discrete fibers with the matrix friction products was studied, which additionally increases the load capacity and reduces the mass intensity of the wear of composites. © 2017 by Begell House, Inc.

Impact toughness of epoxy composite materials reinforced with Al2O3 microparticles of various concentrations were investigated. It is shown that the external (outer) surface layers that form around disperse filler particles is one of the factor responsible their mechanical properties. © 2016 Trans Tech Publications, Switzerland.

We optimize the composition of adhesive and functional surface layers for the formation of two-layer coatings with improved adhesive, physicomechanical, and thermal properties. It is shown that, for the formation of an adhesive layer, it is reasonable to add particles of a carbide mixture in the following amounts: q = 15–20 wt.% per q = 100 wt.% of the epoxy oligomer. At the same time, for the formation of the surface layer of the coating, it is necessary to use q = 40–50 wt.% of iron minium as a filler. © 2015, Springer Science+Business Media New York.

We study the influence of the contents and physical nature of coarse-grained (60-65 μm) and finegrained (3-10 μm) particles on the adhesion strength and residual stresses in epoxy composites for functionally gradient coatings. The temperature-and-time conditions of cross-linking of the epoxy matrix are optimized. The maximum adhesion strength (49.2-50.0 MPa) is attained as a result of the addition of copper-oxide filler (60-65 μm) to the epoxy oligomer in the following amounts: q = 60-80 m.p. per 100 m.p. of the epoxy matrix. The residual stresses vary from 4.5 to 4.8 MPa. © 2013 Springer Science+Business Media New York.
