Universal method of optimal control synthesis offers a versatile method for the synthesis of optimal controls provides a solution to the synthesis problem for the class of piecewise constant functions for Lagrangian dynamical systems, the shape of the control law depends only on the structure of the cost functional and does not depend on the structure of the existing system of generalized forces. The effectiveness of the method is confirmed by a minimum of computational costs, as well as the maximum rate of convergence and accuracy to achieve the desired trajectory in comparison with the known solution for example has become a test for testing various control methods for the synthesis problem of a simple pendulum.

An original mathematical model describing different activities of actors in the vertical marketing system is presented. They are a provider, a agent, a trading enterprise are presented as a controlling subjects. The model is based on the game-theoretical and hierarchical approach. An equilibrium of Germeyer G1 game in terms of sustainable development is established. The method of impulsion is used as a method of hierarchical control to solve this model. The main system operation laws based on numerical experiments are presented.

The article is concerned with problems of modern electrohydraulic converters control systems used to adjust wicket gate of Kaplan turbine. Linearized model of wicket gate servomotor is considered. Algorithm for online identification of parameters of servomotor is considered. Algorithm is based on recurrent least squares method. Algorithm for adaptive PI-regulator tunning is based on online optimization of functional of generalised work (FGW). Model experiments using real data show reducing maximum control error of servomotor position from 20 % to 1 %. Also methods for servomotor state diagnostic are considered.

At present, the development of algorithms is particularly relevant high-level analysis of video sequences, including tracking of objects in a video stream and their implementation in information and communication systems. In the proposed approach the pretreatment step uses optical flow calculation for each frame video sequence, as well as low-level features (such as a representation of each pixel in the color space YIU). For moving objects optical flow is more important than for a stationary background and allows you to find the foreground objects in video sequences and adjust the weighting function in determining the histogram similar to the adjacent frames, taking into account the motion of objects.

The paper reports on dynamical model of optimal biological resource exploitation with corruption. Particularly, it is allowed a fish quota increase after paid a bribe. The research has been realized with the sustainable development conception by the Pontryagin's maximum principle. A time moment, where the bribe is profitable, is considered. Fight corruption methods are presented.
