Model order reduction for a family of linear systems with applications in parametric and uncertain systems
We present an approach which creates a linear reduced order model whose transfer function interpolates at certain given points and approximates at others. We describe how to create the corresponding state space system and explain how this method is used for the simulation of large scale parametric systems or several realizations of an uncertain system. In that case, the interpolation points are...

متن کاملModel Reduction for Compressible Flows using POD and Galerkin Projection
We present a framework for applying the method of Proper Orthogonal Decomposition (POD) and Galerkin projection to compressible fluids. For incompressible flows, only the kinematic variables are important, and the techniques are well known. In a compressible flow, both the kinematic and thermodynamic variables are dynamically important, and must be included in the configuration space. We introd...
متن کاملGalerkin Projection Methods for Solving Multiple Linear Systems
In this paper, we consider using Galerkin projection methods for solving multiple linear systems A (i) x (i) = b (i) , for 1 i s, where the coeecient matrices A (i) and the right-hand sides b (i) are diierent in general. In particular, we focus on the seed projection method which generates a Krylov subspace from a set of direction vectors obtained by solving one of the systems, called the seed ...
متن کاملGuard-based Model Order Reduction for Switched Linear Systems
The principle of model order reduction (MOR) is well-known for enhancing the manageability of large-scale and complex systems. As hybrid dynamical systems are of rising spread and complexity, the application of MOR to such models is of high interest. However, a straightforward applicability is nowadays limited and often of weak performance. In this article, a new performance-improving framework...
