- ДокументAUTOMATIC REGULATOR FOR NON-STATIONARY OBJECTS WITH AN INCREASED RANGE OF NORMAL OPERATION(2017) A. I. PavlovMany objects automatic control unsteady. This is manifested in the change of their parameters. Therefore, periodically adjust the required parameters of the controller. This work is usually carried out rarely. For a long time, regulators are working with is not the optimal settings. The consequence of this is the low quality of many industrial control systems. The solution problem is the use of robust controllers. Explores the possibility of increasing the survivability of automatic control systems by expanding the area of their normal work. This is achieved by using an artificial neural network simple structure. The method is based on the cooperative effect of neural structures. In this block diagram of the controller is very simple. Such control effectively compensates the coordinate perturbations if they act on the control channel.
- ДокументESTIMATION OF THE WIDTH OF THE STATIONARY DETONATION WAVE IN THE MODEL OF ZEL'DOVICH-NEUMANN-DÖRING(2017) A. S. Tityapkin, V. E. VolkovThe models of Chapman-Jouget and Zel'dovich-Neumann-Döring are considered to estimate the width of a detonation wave in gas mixtures. Improved software package was developed earlier. The calculations of stationary detonation wave width are in good agreement with the experimental data. Estimation of the stationary detonation wave width is important for the detonation control.
- ДокументIMPROVED MODELS AND METHOD OF POWER CHANGE OF NPP UNIT WITH VVER-1000(2017) T. Foshch, S. PelykhThis study represents the improved mathematical and imitational allocated in space multi-zone model of VVER-1000 which differs from the known one. It allows to take into account the energy release of 235U nuclei fission as well as 239Pu . Moreover, this model includes sub-models of simultaneous control impact of the boric acid concentration in the coolant of the first circuit and the position of 9th group control rods which allows to consider it as the model with allocated parameters and also allows to monitor changes in the mentioned technological parameters by reactor core symmetry sectors, by layers of reactor core height and by fuel assembly group each symmetry sector. Moreover, this model allows to calculate important process-dependent parameters of the reactor (including axial offset) as quantitative measure of its safety. As the mathematical and imitational models were improved, it allows to take into account intrinsic properties of the reactor core (including transient processes of xenon) and thus reduce the error of modelling static and dynamic properties of the reactor.The automated control method of power change of the NPP unit with VVER-1000 was proposed for the first time. It uses three control loops. One of which maintains the regulatory change of reactor power by regulating the concentration of boric acid in the coolant, the second circuit keeps the required value of axial offset by changing the position of control rods, and the third one holds constant the coolant temperature mode by regulating the position of the main turbo generator valves.On the basis of the above obtained method, two control programs were improved. The first one is the improved control program that implements the constant temperature of the coolant in the first circuit and the second one is the improved control program that implements the constant steam pressure in the second circuit.

- ДокументTHE PROJECT MANAGEMENT OF INDUSTRIAL BUILDINGS REENGINEERING (RECONSTRUCTION AND COMPLETION)(2017) K. Kolesnikova, D. Monova, Ye. Naumenko, I. Kheblov, I. GurjevCreative element fate of any activity may not fall to zero because of the turbulent environment in which these activities are carried out, always prevents this. Environment that makes each building unique, that is, provides the main basis of the project. When we are talking about complex construction, the share of the creative component becomes very significant. First and foremost, this is explained by the duration of the construction work, during which time to happen risk events. The article analyses the processes of construction from the point of view of their conformity to the concept of project activities. It is shown that with increasing degree of difficulty of construction or time of the last share of creative activities in the overall project grows. In recent times more and more widespread work on re-engineering complex systems, for example, building constructions. This means repair of the building, but not a simple repair with restoration of the original, incorporated in the design of building elements and their interfaces, and partial or full replacement of items that fail or are outdated, new ones require first, a new design of their structures and production technologies, as well as the design of the accessories for the installation and technology is reshaping the object. Combining the two above-mentioned factors of growth of the share of creative activities during the project management of the re-engineering of building structures: complexity and construction time, received a cognitive model of such growth. Introduced the concept of "reengineering in construction" as a combination of the processes of adjustment and worn or completion of unfinished buildings. It is proved that any re-engineering in construction is the project activities. Provisions are tested in a real reengineering of industrial buildings with a positive technical and economic effect.
