Smooth extremum-seeking control for fed-batch processes
(Elsevier Science, 2016-09)
Many biotechnological processes have optimal substrate concentrations where a maximum growth rate is achieved. In this work an extremum seeking controller and a gradient estimator are proposed to maximize the growth rate ...
Growth rate maximization in fed-batch processes using high order sliding controllers and observers based on cell density measurement
(Elsevier, 2018-08)
A novel extremum seeking scheme is proposed for the optimization of the specific growth rate in fed-batch processes with substrate inhibited kinetics. The proposed controller is based on a high order sliding mode algorithm, ...
Mixing layer manipulation experiment: From open-loop forcing to closed-loop machine learning control
(Springer, 2015-01)
Open- and closed-loop control of a turbulent mixing layer is experimentally performed in a dedicated large scale, low speed wind-tunnel facility. The flow is manipulated by an array of fluidic micro-valve actuators integrated ...
Performance Improvement by Temperature Control of an Open-Cathode PEM Fuel Cell System
(Wiley VCH Verlag, 2014-06)
The work presented in this article combines experimental analysis and theoretical studies of temperature effects on the performance of an open-cathode, self-humidified PEM fuel cell system for the design of optimal control ...
