Query: Pinning Control of Spatiotemporal Chaos   Linear control theory is used to develop an improved localized control scheme
for spatially extended chaotic systems, which is applied to a Coupled Map
Lattice as an example. The optimal arrangement of the control sites is shown to
depend on the symmetry properties of the system, while their minimal density
depends on the strength of noise in the system. The method is shown to work in
any region of parameter space and requires a significantly smaller number of
controllers compared to the method proposed earlier by Qu and Hu. A nonlinear
generalization of the method for a 1-d lattice is also presented.
