摘要

本文介绍了具有二次输出的线性动力系统的 Krylov 子空间模型阶次缩减。为了实现这一目标，本文考虑了具有两个变量的二次传递函数。在有限频点和无限频点建立了 Krylov 子空间，讨论了单面和双面投影情况。对力矩匹配进行了相应的研究，双面投影情况下产生的还原系统的二次传递函数可以匹配更多的力矩。最后，数值结果说明了所提出的克雷洛夫模型阶次缩减方法的性能。

Krylov subspace model order reduction of linear dynamical systems with quadratic output

This paper presents Krylov subspace model order reduction of linear dynamical systems with quadratic output. To reach this goal, the quadratic transfer function with two variables is taken into consideration. The Krylov subspaces are established at the finite and the infinite frequency points where both the one-sided and the two-sided projection cases are discussed. The moment matching is accordingly studied and the quadratic transfer function of the reduced system resulting from the two-sided projection case can match more moments. Finally, numerical results illustrate the performance of the proposed Krylov model order reduction methodology.
