Description
The article describes the process of creation of an adaptive control system with a reference model to stabilize the temperature of drying agent. It is shown that the closed systems work with the operated models is quite satisfactory and therefore can be implemented in production. The increase of the gain of the controller allows reducing the duration of the transition process by one third, almost without changing the dynamic cast

OPTIMIZATION OF DIGITAL CONTROL SYSTEM OF THE PROCESS OF GRAIN DRYING
DescriptionThe article is a study of digital continuous system and optimization of digital control systems. It is shown that the standard in the synthesis of digital systems should provide a continuous system, so first we need to create the desired continuous system and then we could try to get the digital system closer to it

Description
The article considers the problems of determining the settings area of the control device, which ensure stable operation of the closed system. It shows the solution to the problem using the enhanced amplitude-phase characteristics. The proposed method of finding the domain of stability of parameters of the control device is more simple than classical methods and allows, in general, to find conditions for the stability, not to test the system for stability under given parameters

CONTROLLING SMALL MOVEMENTS OF ULTRA PRECISE DC ELECTRIC DRIVE WITH ELASTIC SHAFTING
DescriptionControl of the movement and positioning are the most intensive tasks of automatic control and regulation. However, these problems must be solved in the automation objects such as assembly and production lines, manufacturing machines, conveyors, hoisting machines, packaging machines, filling lines for liquids, metal-working machines. One problem lies in the fact that all the real drives are connected to the actuators with not perfectly tough shafting, but has some elasticity. This leads to the difficulty of motion of the executive body of the drive automatic control systems which consists of signal source generating signal due optimum speed diagrams for small movements of electric drive’s actuating device and automatic regulation system, which allows to work out optimum speed diagrams for small movements of electric drive’s actuating device with ultra-precision. In this article were developed optimum speed diagram for small movements of ultra-precise electric drive with elastic shafting. Were have identified all parameters of diagrams and its range of existence and also developed a device for generating the optimum speed diagram for small movements of ultra-precise electric drive with elastic shafting. The implementation of the proposed hardware software complex will significantly improve the accuracy of motion actuators of various ultra- precise DC drives

STRATEGIC MANAGEMENT OF A TERRITORIAL DISTRIBUTED COMPLEX
DescriptionThe article is devoted to strategic management and implementation of the strategy. Management strategy is based on the management of strategic potential of the enterprise. The strategic potential of the company generates only those resources that can be changed because of strategic decisions. Analysis of the potential of the enterprise should cover almost all spheres of its activity: the enterprise management, production, marketing, finance, human resources. The article has designed a system of strategic management by the example of a construction company in the information management system territorially - distributed building complexes, thus improving the competitiveness of the organization, to provide timely and quality implementation of business plans
