First, an asymptotic structure along with a stabilizing solution for the stochastic algebraic Riccati equation (ARE) are ne ... [SIAM J.

These tasks may be achieved by recent coverage algorithms, based upon the classic methods by Lloyd. Thes ... [SIAM J.

Wegner<br/> In this paper we study the distributed optimal control for the CahnHilliard system. A general class of free energy potentials is allowed which, in particular, includes the double-obstacle potential. The latter potential yields an optimal control problem of a parabolic variational inequality which i ... [SIAM J.

Roughly speaking, let there be given a s ... [SIAM J.

In this paper we directly and explicitly describe minimal systems in terms of transfer functions. A transfer function is a purely algebraic object that i ... [SIAM J.

As is well known, structural invariants that follow from the definition of cont ... [SIAM J.

Traditional analysis of such algorithms studies, fo ... [SIAM J.

First, it is proved that classical interval observers for systems without delays are not robust with respect to the presence of delays, no matter how small delays are. Next, it ... [SIAM J.

Staffans<br/> We study the problem of strongly coprime factorization over H-infinity of the unit disc. We give a necessary and sufficient condition for the existence of such a coprime factorization in terms of an optimal control problem over the doubly infinite discrete-time axis. In particular, we show that an ... [SIAM J. Control Optim. 50, 266 (2012)] published Thu Jan 19, 2012. http://link.aip.org/link/?SJC/50/243/1&agg=rss C. Canuto, F. Fagnani, and P. Tilli<br/> In this paper we analyze a class of multiagent consensus dynamical systems inspired by Krause's original model. As in Krause's model, the basic assumption is the so-called bounded confidence: two agents can influence each other only when their state values are below a given distance threshold $R$. ... [SIAM J.
