GR decompositions and their relations to Cholesky-like factorizations
arXiv

arXiv 2020年
作者: Benner, Peter Penke, Carolin Computational Methods in Systems and Control Theory Max Planck Institute for Dynamics of Complex Technical Systems Sandtorstr. 1 Magdeburg39106 Germany
For a given matrix, we are interested in computing GR decompositions A = GR, where G is an isometry with respect to given scalar products. The orthogonal QR decomposition is the representative for the Euclidian scalar... 详细信息

Model order reduction via substructuring for a nonlinear, differential-algebraic machine tool model with moving loads
收藏 引用
PAMM 2023年 第1期23卷
作者: Quirin Aumann Peter Benner Jens Saak Julia Vettermann Mathematics in Industry and Technology Faculty of Mathematics Technische Universität Chemnitz Reichenhainer Str. 41 09126 Chemnitz Germany Computational Methods in Systems and Control Theory Max Planck Institute for Dynamics of Complex Technical Systems Sandtorstr. 1 39106 Magdeburg Germany
Machine tools are permanently exposed to complex static, dynamic and thermic loads. This often results in an undesired displacement of the tool center point (TCP), causing errors in the production process and thus lim...
