The article deals with the issues of constructive, structural modeling and automatic control of room heating. The dynamics of the object-the heating system of a residential building-is obtained. Dynamic errors are determined by the dynamic characteristics of the temperature sensor. The design scheme of the object is presented. The heating control system contains three temperature controllers. Using structural modeling, various methods of automatic control of the heating system are evaluated. The technical structure of the automatic temperature control system (ACS) in a residential building is implemented by a cascade three-circuit control with two executive elements. Experimental studies of transients in a closed ACS with three types of regulators are presented. The results obtained make it possible to implement adaptive control of the heating system on a real object.

The results of experimental studies of the effect of electron irradiation on K-208 and CMG glasses used for manufacturing protective coatings of solar batteries and thermal control coatings of space vehicles are analyzed. It is shown that the caused electrostatic discharges lead to structural changes in the surfaces of the glasses studied. The goals of further studies of the influence of proton and electronproton effects on the properties of such coatings are outlined.
