Stabilization of 2D Navier-Stokes equations by means of actuators with locally supported vorticity
Sérgio S. Rodrigues, Dagmawi A. Seifu
Exponential stabilization to time-dependent trajectories for the incompressible Navier-Stokes equations is achieved with explicit feedback controls. The fluid is contained in two-d…

Dynamical observers for parabolic equations with spatial point measurements
Sérgio S. Rodrigues, Dagmawi A. Seifu
An exponential Luenberger dynamical observer is proposed to estimate the state of a general class of nonautonomous semilinear parabolic equations. The result can be applied to the…

Feedback semiglobal stabilization to trajectories for the Kuramoto-Sivashinsky equation
Sérgio S. Rodrigues, Dagmawi A. Seifu
It is shown that an oblique projection based feedback control is able to stabilize the state of the Kuramoto-Sivashinsky equation, evolving in rectangular domains, to a given time-…
