Boundary optimal (LQ) control of coupled hyperbolic PDEs and ODEs
(
Elsevier
, 2013 , Article)
This contribution addresses the development of a linear quadratic (LQ) regulator for a set of hyperbolic PDEs coupled with a set of ODEs through the boundary. The approach is based on an infinite-dimensional Hilbert ...
Optimal control of an advection-dominated catalytic fixed-bed reactor with catalyst deactivation
(
Elsevier
, 2013 , Article)
The paper focuses on the linear-quadratic control problem for a time-varying partial differential equation model of a catalytic fixed-bed reactor. The classical Riccati equation approach, for time-varying infinite-dimensional ...
Nonlinear direct inverse method: A shortcut method for simultaneous calibration and isotherm determination
(2013 , Article)
This work addresses a way to combine isotherm determination and nonlinear calibration. In this method, like the classical inverse method, experimental elution profiles are compared with the results of a detailed model that ...
