The article studies the thermal conditions in the heating system of a two-storey building of the laboratory building of the Medical Institute. The analysis was carried out on the basis of data obtained from thermograms of heating devices. The study of thermal conditions in a two-pipe heating system is carried out, the actual and estimated power of each heating device is determined, as well as the temperature inside the premises.

The article reveals the results of the work carried out on modeling the dynamic model of the electric drive of the scanning mechanism of the Earth orientation device, which is based on a hybrid stepping motor. The simulation is based on NEMA 17HS3410 motor parameters. A brief description and features of hybrid stepper motors are provided. The simplest model of an electric drive is considered, in which there is a rigidly set moment of force, a moment of inertia of the rotor of an electric motor, and also the moments of dry friction and the moment of liquid friction are taken into account. It is shown how the change in the value of fluid friction affects the general behavior of the mathematical model of a hybrid electric motor. The behavior of a single-pole stepper drive is simulated. The relationship of the value of the moment of force acting on the rotor with the passport characteristics of the investigated electric motor is considered. The possibility of controlling the scanning mechanism based on P- and PI-controllers is estimated.

The article describes the slow flying drones with reference to problems of aerial photography. As an alternative to multicopter proposed aerodynamic design, elliptical flying wing. It has been shown that this scheme allows ensure uniform distribution of lifting force along the wing span, respectively, does not allow on loss of unmanned speed bogged down into a tailspin. The results of mathematical modeling and flight test a prototype of this type of UAV.

In the article a number of approaches to a flapping wing pilotless vehicle control system synthesis are analyzed. Referred type of pilotless vehicles is possessed of a number of advantages compared to the traditional schemes, but requires a special approach to control system creation because of strong nonlinearity and multicoupling of a controlling object mathematical model. As a result of a control system synthesis approaches analysis a synergetic approach was marked out as the most adequate for the mentioned above type of controlling objects. An idea of prognostics application for the goal of reaching of adaptive control is also set forth. In this case parameters of an object of control and parameters of ambient both are to be forecasted whereby an adaptive behavior of an object of control is expected to be achieved.
