Virtual sensor development for continuous microfluidic processes 2020 In continuous microfluidic processes, such as factory-on-chips, most valuable variables to be sensed for implementing an optimal control are usually not accessible. This is, for instance, the case of the shape and position tracking of the flow interfaces in a flow-focusing microdevice. In this context, virtual sensors are promising tools to improve the current control systems aiming at a zero-defect strategy. This article presents a methodology for building an accurate virtual sensor, based on computer-aided engineering simulations, both analytical and numerical, and model order reduction techniques. The methodology is applied to a given flow-focusing microchip. The outcome is a real-time model (virtual sensor) able to predict the shape and location of the multiphase fluid interfaces from the volumetric flow rate measured in the system. Results are successfully validated against the experimental data. The main challenge of this approach is to minimize uncertainties associated with the microfluidics setup. info:eu-repo/grantAgreement/EC/H2020/680481/EU/Third tranche of Success Stories/Fortissimo 2 This project has received funding from the European Union’s Horizon 2020 research and innovation program under grant agreement No H2020 680481-Fortissimo 2 info:eu-repo/semantics/closedAccess All rights reserved http://www.europeana.eu/rights/rr-f/ 10.215 2020 AUTOMATION & CONTROL SYSTEMS 4 / 63 = 0.063 2020 Q1 T1 ENGINEERING, INDUSTRIAL 1 / 49 = 0.02 2020 Q1 T1 COMPUTER SCIENCE, INTERDISCIPLINARY APPLICATIONS 3 / 111 = 0.027 2020 Q1 T1 2.496 2020 Computer Science Applications 2020 Q1 Information Systems 2020 Q1 Electrical and Electronic Engineering 2020 Q1 Control and Systems Engineering 2020 Q1 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Bengoechea-Cuadrado, C.
