H-1 HEAT EXCHANGER TEMPERATURE CONTROL SYSTEM 97, 99, 112
A heat exchanger temperature control system of a pasteurization process is analyzed in this Appendix as an example to applied the non-diagonal MIMO QFT tracking design methodology introduced in chapter 10. The plant PCT23, manufactured by Armfield (UK),127 is a miniature version of a real High Temperature Short Time (HTST) pasteurization process (Fig. H.1). It consists of a bench-mounted process unit connected to a control console to provide access to the measured and control signals.
