Abstract
Very recently it has been shown that controlling weak turbulent flows without feedback by a driving force which has a nonsinusoidal time dependence and a smooth spatial dependence might be possible, if the dynamics of the unperturbed flow can be modeled by a low dimensional model. In this paper we show that control might be possible in cases where the parameters of the model have a complicated unpredictable time dependence. The basic idea is to measure from time to time, the response of the experimental system in order to adjust the model. We investigate the magnitude of the deviations between goal dynamics and experimental dynamics and discuss the influence of noise.
