Academician A. N. Krylov Method in the Problem of Linear Model Construction in the Rigion of Images
The problem of image representation of solutions of the linear stationary system with minimal polynomials of the state space is considered. On this basis, a generalization of the A. N. Krylov, allowing in the non determinant form of a complete description of eigen-movements and reactions of the system. In combination with an effective procedure for constructing the minimal polynomials of the proposed approach extends the possibilities of large-scale systems research in particular with the application of computer technology.

Linearization for a Class of Nonlinear Models
This paper considers a scheme of linearizing compensator for parallel Hammerstein model. The compensator exactly linearizes the system via the internal feedback without truncation of Volterra series. Using the compensator with online identification determines adaptive linearization. Keywords: linearization, compensator, parallel hammerstein model

Method of the Combined Conceptual Modelling of Technical Systems
Is offered the method of conceptual modelling of technical systems (TS), based on the combined application of known methods of the structurally functional analysis, object-oriented and joint objective-functional modelling. The useful effect gained thus consists in simplification of problem solving of construction of conceptual models of a design, managerial processes by states and operated functioning of the TS at the expense of use of potentials in acquisition and use of the complementary information got during application of the specified methods of modelling.
Keywords: the theory of technical systems, conceptual models of systems and processes, methods of conceptual modelling

Research of Efficiency of Control Systems of Nonlinear Second-Order
Dynamic Objects with Extreme Static Characteristic
The article investigates the features of the three control systems of nonlinear dynamic objects with extreme static characteristic, namely control system, which realizing the optimal control in the form of a piecewise continuous function, the control system, realizing quasi-optimal control in the form of a continuous function and the control system, realizing adaptive control. Control laws for the first two systems are found on the basis of the Pontryagin maximum principle applied to nonlinear objects. The third control system is realizing on the PID controller with variable gain. Control systems compared to the minimum resource consumption in the transition process, at the transient time, on the asymptotic stability in the endpoint, and overshoot.
Keywords: nonlinear dynamic object, extreme static characteristic, Pontryagin maximum principle, special control, optimal adaptive control, PID control, customizable controller gain
