Development of models and software tools for the creation of a robust control system exchanger

The article describes the development of a mathematical model, mathware and software for steam-liquid heat exchanger robust control system design. The article spotlights the problem actuality and difficulties of its solving. The advantage of proposed algorithm for the exchanger model design is a minimal number of input variables, namely initial and final temperature of the liquid, mass flow rate of the liquid, pressure in the steam line. The algorithm includes constructive design, calculation of losses, calculation of the control valve, calculation of the heat exchanger dynamic model, calculation of the temperature sensor dynamic model and design of robust controller for the closed-loop control system. The algorithm of constructive design allows choosing a heat exchanger from standard line. The software implements developed mathware. The analysis of transient processes of closed-loop control system worked under the set of the exchanger loads proves the robustness of the system
