Abstract: Possibilities of using robust controllers for a shell-and-tube heat exchanger control were studied, tested and compared by simulations and obtained results are presented in this paper. The heat exchanger was used to pre-heat petroleum by hot water; the controlled output was the measured output temperature of the heated fluid – petroleum, and the control input was the volumetric flow rate of the heating fluid – water. Robust controllers were designed using H2, H∞, H2/H∞ strategies and μ-synthesis. A comparison with the classical PID control demonstrated the superiority of the proposed robust control especially in case when the controlled process is affected by disturbances.

Keywords: heat exchanger, PID control, H2 control, H∞ control, μ-synthesis
