We report control of chemical chaos observed during the electrodissolution of a rotating copper disc in a sodium acetate/acetic acid buffer. An adaptation of a simple recursive proportional-feedback control strategy, generally applicable to systems well described by one-dimensional maps, was used to stabilize the chaotic response of the system on an unstable period-one orbit. The successive minima in the measured anodic current generated a return map that was used to characterize the dynamics and the control algorithm prescribed small changes in the anodic potential to affect the control.
