At the present stage of development of automatic control systems raises the question of maintaining the set temperature objects. The authors developed MetO-wild synthesis of nonlinear regulators to stabilize the temperature field, a uniform object of management on the basis of a given error. We obtained a function of the initial heating and the mathematical modeling of the process, analyzed the results. By creating a regulator there has been designed software and hardware programming language Pascal, which allows to simulate the behavior of temperature fields in an isotropic web. It is a simulation of the temperature of the system in different configurations: with different amounts of pulsed heating sources with relay control principle. Practical results of the research suggest the possibility of constructing silicon carbide heating element made in the form of an isotropic core.
The article deals with the design and operation of a steam generating unit through the example of the reactor core RBMK-1000 (High Power Channel-type Reactor). It contains the description of the equipment being a part of the multiple forced circulation circuits (MFCC), which form the reactor. Careful consideration is given to the process of controlling the coolant flow in the reactor fuel channels via shut-off control valve (SOCV) and the necessity of its (the process) automation. The problem of SOCV automatic control system synthesis is formulated and solved. The possibility of using a device with extended frequency response (EFR) for a frequency response analysis of distributed parameter systems (DPS) is considered. The problem of developing a method for calculating the settings of the distributed PID-controller is formulated and solved. Software for the simulation of thermal field in the reactor core is developed.
