Abstract

We report results (numerical and experimental) indicating control of the observed oscillatory dynamics in an electrochemical system using external forcing and variable feedback. Under the influence of external forcing it was observed that the chaotic dynamics could be converted to periodic states. Moreover, regular states with different periodicities could be stabilized. Using a continuous delayed feedback control strategy chaotic oscillations are suppressed via stabilization of fixed point steady states and/or periodic dynamics. Finally we report numerical results indicating control of spatiotemporal chaos observed in a spatially extended chemical system. In one spatial dimension the model dynamics under appropiate parameter conditions exhibit chemical turbulence which is suppressed using feedback and forcing techniques.
