An Invariance Problem for Control Systems with Deterministic Uncertainty

Lech GórniewiczPaolo Nistri — 1996

Banach Center Publications

This paper deals with a class of nonlinear control systems in R n in presence of deterministic uncertainty. The uncertainty is modelled by a multivalued map F with nonempty, closed, convex values. Given a nonempty closed set K R n from a suitable class, which includes the convex sets, we solve the problem of finding a state feedback ū(t,x) in such a way that K is invariant under any system dynamics f. As a system dynamics we consider any continuous selection of the uncertain controlled dynamics F.

A Tikhonov-type theorem for abstract parabolic differential inclusions in Banach spaces

Anastasie GudovichMikhail KamenskiPaolo Nistri — 2001

Discussiones Mathematicae, Differential Inclusions, Control and Optimization

We consider a class of singularly perturbed systems of semilinear parabolic differential inclusions in infinite dimensional spaces. For such a class we prove a Tikhonov-type theorem for a suitably defined subset of the set of all solutions for ε ≥ 0, where ε is the perturbation parameter. Specifically, assuming the existence of a Lipschitz selector of the involved multivalued maps we can define a nonempty subset Z L ( ε ) of the solution set of the singularly perturbed system. This subset is the set of...

On the existence of periodic solutions of an hyperbolic equation in a thin domain

Russell JohnsonMikhail KamenskiiPaolo Nistri — 1997

Atti della Accademia Nazionale dei Lincei. Classe di Scienze Fisiche, Matematiche e Naturali. Rendiconti Lincei. Matematica e Applicazioni

For a nonlinear hyperbolic equation defined in a thin domain we prove the existence of a periodic solution with respect to time both in the non-autonomous and autonomous cases. The methods employed are a combination of those developed by J. K. Hale and G. Raugel and the theory of the topological degree.
