The retrospective and limited identification problems in integrated form of the systems of filtration–consolidation in compressible media of microporous particles using the residual functional, taking into account the total liquid flow change on the observation surface are formulated. Highly productive methods of identification problems realization in integrated form based on the analytical solutions of the direct problems are proposed. Explicit analytical expressions of components of residual functional gradients for identifying model conditions parameters by the gradient methods are obtained.

A geo-referencing method for an isolated ground object using results of space imaging without previous in-flight geometric calibration of spacecraft's optical-electronic complex is proposed. The equations of the geo-referencing directly take into account indefiniteness of mutual attitude of onboard
imaging camera and star tracker. Such a way may be effective if necessary information for in-flight geometric calibration is inaccessible.

The mathematical models of the weight-and-size and thermal
characteristics of hermetically sealed stackable design units are generated. The relations are obtained for determining the optimal number of printed circuit boards, the distances between the boards and the diameter of the racks. The method of weight-and-size optimization of hermetically sealed stackable design unit is proposed. Temperature distribution simulation in the unit is
carried out by CAE system.

Problem of optimal operation speed for linear systems with fractional derivatives in the Riemann–Liouville sense is under consideration. By means of the methods of convex analysis and theory of multivalued mappings we constructed optimal controls and obtained sufficient conditions of optimality. Theoretical results are shown in practice.

Potential of development of the Kharitonov method for investigation of robust stability of systems with interval parameters is considered. Notion of relative interval is used in the research. For visualization of robustly stable processes virtual multichannel system is constructed. For construction of
channels of the virtual system we used the "Kharitonov" polynomials. Theoretical investigations are shown by the examples.

The paper contains the theoretical backgrounds and methods of finding the system of modules of modified perfect form of the system of residual classes, thus reducing the computational complexity by avoiding the most labor-intensive operation − finding the inverse element by module. The proposed theory is presented on examples of a three-modules system and is
a background for the calculation of the modified perfect form of the system of residual classes for the greater number of modules.

The paper studied the inverse problem for equations connected with
flexural-torsional vibrations of a bar. This problem is reduced to an optimal control problem and studied by the methods of optimal control theory. The necessary and sufficient optimality condition is proved.

For the processes, described by the initial-boundary value problem for a linear partial differential equation of the third order the optimal control is constructed using the method of moments. In addition, at first it is obtained the representation of the solution of the initial-boundary value problem by the method of separation of variables. Further, applying the method of moments, it is constructed an optimal control in the form of the double row and the convergence of this row is proved.
