Suppression of chemical turbulence using feedbacks and forcing

We report the suppression of spatiotemporal chaos observed in a spatially e xtended chemical system, In one spatial dimension, under appropriate parame ter conditions the model system exhibits transition to turbulence via backf iring of pulses. Suppression is achieved using different feedback and forci ng techniques, some of which are applicable in actual experimental situatio ns. Results from the application of some of these strategies to a single (u ncoupled) oscillator (two-dimensional O.D.E (ordinary differential equation s) system) are presented to demonstrate similarities in the dynamical respo nse of a single system and an extended system under the influence of extern al feedbacks.
