Distillation column monitoring requires shortcut nonlinear dynamic models. On the basis of a classical wave-model and time-scale reduction techniques, we derive a one-dimensional partial differential equation describing the composition dynamics where convection and diffusion terms depend non-linearly on the internal compositions and the inputs. The Cauchy(More)
The goal of our work is to optimise the supply chain management of industrial assets with UHF RFID system. This allows simple identification. In this work, we try to go further and enrich the identification information with information about the conditions of the connected assets. To avoid any maintenance operation, we realise an energy harvesting circuit(More)
Purity control in distillation columns often relies on linear models whose parameters (gains, delays, time constants) may be hard to fit satisfyingly. In this paper, we linearize a convection-diffusion model inspired from wave-models, in the case of vanishing diffusion. We obtain a linear transfer model which is explicitly parameterized with the usual(More)
