Stability margins and model-free control: A first look
We show that the open-loop transfer functions and the stability margins may
be defined within the recent model-free control setting. Several convincing
computer experiments are presented including one which studies the robustness
with respect to delays.Comment: 13th European Control Conference, Strasbourg : France (2014
Model-based versus model-free control designs for improving microalgae growth in a closed photobioreactor: Some preliminary comparisons
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.Comment: The 24th Mediterranean Conference on Control and Automation (MED'16),
