Control of Linear and Nonlinear Systems

This minisymposium addresses topics in control of large systems, with emphasis on models described by linear and non-linear partial differential equations. The speakers will discuss exact controllability questions for linear P.D.E.s by boundary controls and connections with scattering theory to min-max and max optimization for linear systems design, stability questions, or lack thereof, of non-linear P.D.E.s such as the KdV equation and wave-Petrowski systems with dissipation. The presentations provide and blend applied mathematics and theoretical engineering perspectives which are brought to bear in the solution of physically significant problems.
