Practical verification of the control strategies for the counter-current heat exchanger

Abstract

This paper shows the experimental results of the control of the heat exchanger working as a part of the laboratory heat exchange and distribution pilot plant. Two control strategies are considered: PI + gain scheduling (PI+GS) technique and Balance-Based Adaptive Control (B-BAC) methodology. In both cases, simplified modeling of different type is required and the results of the comparative tests show the control performance of both strategies when the flow rate of the heating medium is the manipulated variable.
