Delayed-output-controlled chemical oscillations

Research output: Contribution to journalArticlepeer-review


The rate of in-flow in a continuous-flow stirred-tank reactor is controlled by the concentration of one of the reactor species at some previous time. This control delay has been investigated both theoretically and experimentally for the minimal bromate oscillator. The period of the controlled oscillations increases and decreases as a function of the delay time in a "sawtooth" fashion with overlapping regions of birhythmicity. The experimental results are in good agreement with those calculated with the Noyes-Field-Thompson mechanism.
