Using weighted global control for stabilizing patterned states.

Chaos (Woodbury, N.Y.)

Panfilov V, Sheintuch M.
PMID: 12779803
Chaos. 1999 Mar;9(1):78-87. doi: 10.1063/1.166381.

A general method to control a desired patterned state in reaction-diffusion processes is presented. Weighted global control is aimed to keep weighted spatially averaged properties of state variable at preset values. It is shown that weighted global control creates...
