Abstract:
Model‐reduction techniques aim to reduce the computational complexity of simulating dynamical systems by applying a (Petrov–)Galerkin projection process that enforces the dynamics to evolve in a low‐dimensional subspace of the original state space. Frequently, the resulting reduced‐order model (ROM) violates intrinsic physical properties of the original full‐order model (e.g., global conservation, Lagrangian structure, state‐variable bounds) because the projection process does not generally ensu...     »
