For chemical reactors with non-linear fluid dynamics, a linear model realisation is proposed. The inputs are the ingoing concentration of a certain component in the fluid, and the reaction rate. The...
Modeling and control of water disinfection process in annular photoreactors (2007)
Keesman, K.J., Vries, D., Van Mourik, S., Zwart, H.J.
As an alternative or addition to complex physical modeling, in this paper transfer function models of the disinfection process in annular photoreactors under different flow conditions are derived....
Modelling and controller design for a UV disinfection plant (2007)
Van Mourik, S., Geurts, B.J., Zwart, H.J.
A mathematical model describing fluid flow and concentration dynamics of microorganisms inside a UV photoreactor is developed. Using physical arguments and techniques from system theory, we...
Van Mourik, S., Zwart, H.J., Keesman, K.J.
For a class of scalar nonlinear systems with switching input a controller is designed using design theory for linear systems. A stability criterion is derived that contains all the physical system...
Analytic control law for a food storage room (2007)
Van Mourik, S., Zwart, H.J., Keesman, K.J.
A storage room contains a bulk of potatoes that produce heat due to respiration. A ventilator blows cooled air around to keep the potatoes cool and prevent spoilage. The aim is to design a control...
Climate control of a bulk storage room for foodstuffs (2006)
Van Mourik, S., Zwart, H.J., Keesman, K.J.
A storage room contains a bulk of potatoes that produce heat due to respiration. A ventilator blows cooled air around to keep the potatoes cool and prevent spoilage. The aim is to design a control...
