Design Optimization Using Hyper-Reduced Order Models
1. Abstract Partial Differential Equation (PDE)-constrained optimization requires the solution of large-scale systems of equations at each iteration of the design process. The size of such systems scales with the dimension of the discretized model associated with the PDE and incurs large CPU costs and memory requirements. In the present work, projection-based reduced-order models (ROMs) [1] are...
متن کاملOptimization of IGCC processes with reduced order CFD models
Integrated gasification combined cycle (IGCC) plants have significant advantages for efficient power generation with carbon capture. Moreover, with the development of accurate CFD models for gasification and combined cycle combustion, key units of these processes can now be modeled more accurately. However, the integration of CFD models within steady-state process simulators, and subsequent opt...
متن کاملOptimal Control of Multiscale Systems Using Reduced-order Models
We study optimal control of diffusions with slow and fast variables and address a question raised by practitioners: is it possible to first eliminate the fast variables before solving the optimal control problem and then use the optimal control computed from the reduced-order model to control the original, high-dimensional system? The strategy “first reduce, then optimize”—rather than “first op...
متن کاملFeedback control of flow resonances using balanced reduced-order models
This paper investigates the use of balanced reduced-ordermodels for the feedback control of flow resonances. Specifically, the Eigensystem Realization Algorithm is used to find balanced reduced-order models of the linear dynamics of such flow resonances. The method is applied first to a computational problem in direct numerical simulations of Although the resulting reduced-order models both hav...
متن کاملReduced-order Reference Models for Adaptive Control of Space Structures
Reduced-Order Reference Models for Adaptive Control of Space Structures Alexander I. Scherling In addition to serving as a brief overview of aspects relevant to reducedorder modeling (in particular balanced-state and modal techniques) as applied to structural finite element models, this work produced tools for visualizing the relationship between the modes of a model and the states of its balan...
