Abstract

We demonstrate that rare intense events in the complex Ginzburg-Landau equation can be suppressed by using only observation-based control. Our control strategy eliminates the requirements of a precise system model and prediction. Analytic insights for guiding the control and numerical verification are obtained. The issue of time delay is also addressed. We expect our results to provide insight into the challenging problem of harnessing spatially extended complex systems.
