ITERATIVE DESIGN OF CONTROL SYSTEMS: AN APPROACH TO OVERCOME THE RESONANT EFFECT ON HEAT EXCHANGERS

This paper deals with the control of the heat exchangers. Due to the resonant effect on this systems, simplified lumped parameters models obtained from the step response can be not enough appropriate to controller design if high performance is required. To design the control, instead of looking for a precise heat exchanger model obtained through complex experiments and sophisticated parameter estimation methods, the use of an iterative approach is suggested.
