Finding optimal operating modes for bioprocesses has been, for a long time, a relevant issue in bioengineering. The problem is of special interest when it implies the simultaneous optimization of competing objectives. In this paper, we address the problem of finding optimal steady states that achieve the best tradeoff between yield and productivity by using nonmodel ‐ based extremum‐seeking control with semiglobal practical stability and convergence properties. A special attention is paid to… 
Model-Free Extremum Seeking Control of Bioprocesses: A Review with a Worked Example
TLDR
A review of the past and current trends in model-free extremum seeking is proposed with an emphasis on finding optimal operating conditions of bioprocesses and some experimental case studies are discussed.
Extremum seeking from 1922 to 2010
Extremum seeking is a form of adaptive control where the steady-state input-output characteristic is optimized, without requiring any explicit knowledge about this input-output characteristic other
Lyapunov-based continuous-stirred tank bioreactor control to maximize biomass production using the haldane and monod specific growth models
A novel robust controller is proposed for a continuous-stirred tank bioreactor that controls the culture dilution rate into the bioreactor in order to maximize a cost function representing the
A unifying approach to extremum seeking: Adaptive schemes based on estimation of derivatives
TLDR
It is shown how extremum seeking can be achieved by combining an arbitrary continuous optimization method with an estimator for the derivatives of the unknown steady-state reference-to-output map to ensure non-local convergence of all trajectories to the vicinity of the extremum.
A unifying framework for analysis and design of extremum seeking controllers
TLDR
A unifying design approach to continuous-time extremum seeking based on a feedback control paradigm that provides a direct link to off-line optimization and can be used as a unifying framework for design of novel extremity seeking schemes is summarized.
Bioprocess Control: Current Progress and Future Perspectives
TLDR
It is elucidated that bioprocess control is more than just automation, and includes aspects such as system architecture, software applications, hardware, and interfaces, all of which are optimized and compiled as per demand.
Bacteria foraging optimization-based extremum seeking control
A bacteria foraging optimization-based extremum seeking control (ESC) scheme is proposed. In the scheme, the system states are guided to the optimal point by the controller based on the online
