Distributionally Robust Chance Constrained Data-Enabled Predictive Control [PDF]

open access: yesIEEE Transactions on Automatic Control, 2020
In this article we study the problem of finite-time constrained optimal control of unknown stochastic linear time-invariant (LTI) systems, which is the key ingredient of a predictive control algorithm—albeit typically having access to a model. We propose

Energy and reserve dispatch with distributionally robust joint chance constraints

open access: yesOperations Research Letters, 2021
We develop a two-stage stochastic program for energy and reserve dispatch of a joint power and gas system with a high penetration of renewables. Data-driven distributionally robust chance constraints ensure that there is no load shedding and renewable ...

Deep self-learning enables fast, high-fidelity isotropic resolution restoration for volumetric fluorescence microscopy

open access: yesLight: Science & Applications, 2023
One intrinsic yet critical issue that troubles the field of fluorescence microscopy ever since its introduction is the unmatched resolution in the lateral and axial directions (i.e., resolution anisotropy), which severely deteriorates the quality ...
