Controllability results for weakly blowing up reaction-diffusion system

Electronic Journal of Qualitative Theory of Differential Equations, 2012
In this paper, we consider the controllability of a general reaction-diffusion system with homogeneous Dirichlet boundary conditions. We prove the exact controllability to the trajectories and the approximate controllability of the system which contains ...

Analysis of the three dimensional heat conduction in nano- or microscale [PDF]

, 2010
The Dual-Phase-Lagging (DPL) equation is formulated as an abstract differential equation. In the absence of a heat source term the DPL equation with homogeneous boundary conditions generates a contraction semigroup.

An abstract approximate controllability result and applications to elliptic and parabolic systems with dynamic boundary conditions

Electronic Journal of Differential Equations, 2001
In this paper we prove an approximate controllability result for an abstract semilinear evolution equation in a Hilbert space and we obtain as consequences the approximate controllability for some classes of elliptic and parabolic problems subjected to ...

Control Problems for Semilinear Neutral Differential Equations in Hilbert Spaces

The Scientific World Journal, 2014
We construct some results on the regularity of solutions and the approximate controllability for neutral functional differential equations with unbounded principal operators in Hilbert spaces.

Inverse problem for a parabolic system with two components by measurements of one component

, 2008
We consider a $2\times 2$ system of parabolic equations with first and zeroth coupling and establish a Carleman estimate by extra data of only one component without data of initial values.

Retrofit control with approximate environment modeling

Automatica, 2019
In this paper, we develop a retrofit control method with approximate environment modeling. Retrofit control is a modular control approach for a general stable network system whose subsystems are supposed to be managed by their corresponding subsystem operators.

Approximate controllability of neutral stochastic integro-differential systems with impulsive effects

Electronic Journal of Differential Equations, 2016
