Abstract

We discuss minmax compensator design for the driven cavity problem. A nonlinear controller is obtained by using a linear feedback control law with nonlinear compensator equations. A finite difference-Galerkin scheme with divergence free basis is applied to the infinite dimensional system to illustrate the feasibility of this approach
