Non-competitive L2/D control applied to continuous concentric tubes heat exchanges

L2/D proportional integral (PI) control was applied to continuous concentric tubes heat exchangers as example of space distributed parameter systems, both in SISO and MIMO structures. Dynamic model was expressed in continuous space state and leaded to demonstrate that L2/D control is a class of parametric geometric control. Results show that proposed control applied in heat exchangers, gives similar performance and robustness with less parameters than previous geometric controls reported in literature in SISO structures. The proposed L2/D PI control was easily extended to MIMO structure.
