“…[ 35,36 ] However, in the case of chemical and/or materials processing systems, the link between energy and/or entropy as main thermodynamical properties to the dynamical systems description is not transparent, and current important contributions strive to introduce a physical insight into dynamical systems theory applied to the chemical and materials process control realizations in the sense that the insight accounts for both the conservation of total energy and for the irreversible entropy production. [ 37,39,40 ] There are several ‘thermodynamic’ dynamical models developed, see more in Ramirez et al [ 38 ] and this indeed represents a promising and a challenging path in future developments and efforts.…”
