Computation of conformal invariants
(
Elsevier
, 2020 , Article)
We study numerical computation of conformal invariants of domains in the complex plane. In particular, we provide an algorithm for computing the conformal capacity of a condenser. The algorithm applies to a wide variety ...
Boundary optimal control design for a system of parabolic-hyperbolic PDEs coupled with an ODE
(
Taylor and Francis Ltd.
, 2020 , Article)
This paper deals with the design of a boundary optimal controller for a general model of parabolic-hyperbolic PDEs coupled with an ODE. The augmented infinite-dimensional state-space representation has been used in order ...
Control of parabolic PDEs with time-varying spatial domain: Czochralski crystal growth process
(
Taylor and Francis Ltd.
, 2013 , Article)
This paper considers the optimal control problem for a class of convection-diffusion-reaction systems modelled by partial differential equations (PDEs) defined on time-varying spatial domains. The class of PDEs is characterised ...
Infinite-dimensional LQ optimal control of a dimethyl ether (DME) catalytic distillation column
(
Elsevier
, 2012 , Article)
This contribution addresses the development of a linear quadratic (LQ) regulator in order to control the concentration profiles along a catalytic distillation column, which is modelled by a set of coupled hyperbolic partial ...
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 ...
Duality-based optimal compensator for boundary control hyperbolic PDEs system: Application to a tubular cracking reactor
(
Elsevier

This paper is devoted to the design of an optimal stabilizing compensator for a boundary control distributed parameter system that is described by a set of hyperbolic partial differential equations (PDEs). The standard ...
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 ...
Optimal control and duality-based observer design for a hyperbolic PDEs system with application to fixed-bed reactor
(
Taylor and Francis Ltd.
, 2021 , Article)
This paper is devoted to the design of an optimal infinite-dimensional Luenberger observer combined with a linear-quadratic state feedback controller for a system of hyperbolic PDEs. The design is based on the duality fact ...
Optimal boundary control of coupled parabolic PDE-ODE systems using infinite-dimensional representation
(
Elsevier
, 2015 , Article)
The optimal boundary control problem is studied for coupled parabolic PDE-ODE systems. The linear quadratic method is used and exploits an infinite-dimensional state-space representation of the coupled PDE-ODE system. ...
Spectral-based optimal output-feedback boundary control of a cracking catalytic reactor PDE model
(
Taylor and Francis Ltd.
, 2024 , Article)
This research paper focuses on the design of a boundary optimal controller with output feedback for a tubular catalytic cracking reactor. The process is represented by a set of non-linear parabolic partial differential ...
