Non-competitive L2D control applied to continuous concentric tubes heat exchangers

Abstract

Non-competitive geometric nature of L2D controls was shown and its potential was demonstrated by applying L2D proportional integral (PI) algorithms to continuous concentric tubes heat exchangers (CCTHE) as example of space distributed S.A. Medina-Moreno, S. Huerta-Ochoa, C.A. Lucho-Constantino, L. Aguilera-Vázquez, A. Jiménez González y M. Gutiérrez-Rojas parameter systems. Both SISO (single input single output) and decentralized MIMO (multiple input multiple output) structures were applied. Dynamic models of CCTHE were expressed in continuous space state. Results show that SISO L2D PI algorithm applied to the heat exchanger, gives similar performance and robustness with less parameters than previous geometric controls reported in literature. The proposed L2D PI algorithm was easily extended to decentralized MIMO structure.
