Model-based versus model-free control designs for improving microalgae growth in a closed photobioreactor: Some preliminary comparisons

11 May 2016  ·  Tebbani Sihem, Titica Mariana, Join Cédric, Fliess Michel, Dumur Didier ·

Controlling microalgae cultivation, i.e., a crucial industrial topic today, is a challenging task since the corresponding modeling is complex, highly uncertain and time-varying. A model-free control setting is therefore introduced in order to ensure a high growth of microalgae in a continuous closed photobioreactor... Computer simulations are displayed in order to compare this design to an input-output feedback linearizing control strategy, which is widely used in the academic literature on photobioreactors. They assess the superiority of the model-free standpoint both in terms of performances and implementation simplicity. read more
