Abstract
  • A simple heat exchanger network has been studied as an example of a dynamically interactive process. The process is relatively simple, requiring only temperature measurements and flow rate manipulations. Equations are presented for the design of a physical process having a specified steady-state Relative Gain Array and specified dynamic characteristics. Although the physical process is simple, it is shown to be a challenging control problem. The design equations were used to fit data from existing equipment and to design a simpler configuration which has significant dynamic interactions but only small steady-state interactions. This simple configuration was simulated and the performances of two Proportional-Integral controllers or an Internal Model Controller were compared. Only the IMC controller showed satisfactory control of the process.
