A novel approach is presented to constrain reduced-order models (ROM) based on proper orthogonal decomposition (POD). The ^ 7 Karush–Kuhn–Tucker (KKT) conditions were applied to the traditional reduced-order model to constrain the solution to user8 defined bounds. The constrained reduced-order model (C-ROM) was applied and validated against the analytical solution to the 9 first-order wave equation. C-ROM was also applied to the analysis of fluidized beds. It was shown that the ROM and C-ROM 10 produced accurate results and that C-ROM was less sensitive to error propagation through time than the ROM.
