论文摘要
本文从优化的角度重新审视了模态截断。特别是,主导杆的概念是相对于不同的系统规范作为相关最佳模态截断问题的解决方案的。后者被重新列为等效的凸整数或混合整数程序。数值示例突出了概念和优化方法。
This paper revisits the modal truncation from an optimisation point of view. In particular, the concept of dominant poles is formulated with respect to different systems norms as the solution of the associated optimal modal truncation problem. The latter is reformulated as an equivalent convex integer or mixed-integer program. Numerical examples highlight the concept and optimisation approach.
