Nonadaptive Learning in Robust Nonlinear Output Regulation
Shimin Wang, Martin Guay, Richard D. Braatz
This paper considers robust nonadaptive regulation for general nonlinear systems in an output-feedback setting with arbitrarily high relative degree. We develop a nonadaptive desig…
A Lego Block Approach to Flow in Complex Microfluidic Networks
Etienne Boulais, Richard D. Braatz
We present a new way to construct analytical solutions for flow in complex microfluidic channel networks, as well as planar disordered media. Using a combination of Schwarz-Christo…
Least-Squares Multi-Step Koopman Operator Learning for Model Predictive Control
Liang Wu, Wallace Gian Yion Tan, Leqi Zhou +2
MPC is widely used in real-time applications, but practical implementations are typically restricted to convex QP formulations to ensure fast and certified execution. Koopman-based…
Mechanistic Modeling of Continuous Lyophilization for Biopharmaceutical Manufacturing
Prakitr Srisuma, Gang Chen, Richard D. Braatz
Lyophilization (aka freeze drying) is a typical process in pharmaceutical manufacturing used for improving the stability of various drug products, including its recent applications…
Arbitrarily Small Execution-Time Certificate: What was Missed in Analog Optimization
Liang Wu, Ambrose Adegbege, Yongduan Song +1
Numerical optimization (solving optimization problems using digital computers) currently dominates but has three major drawbacks: high energy consumption, poor scalability, and lac…
Advanced Characterization Methods for Crystals of an Extraordinary Material
Vivekananda Bal, Jackie M. Wolfrum, Paul W. Barone +4
Physicochemical characterization of materials is central to the field of science and engineering and is essential to design new/engineered materials with specific properties. Assay…
