Balanced truncation model reduction for symmetric second order systems -- A passivity-based approach

Ines Dorschky, Timo Reis, Matthias Voigt

摘要:

本文提出了一种基于正实平衡截断的线性定常二阶系统模型降阶方法。我们的方法保证了降阶模型的渐近稳定性和无源性以及质量矩阵和刚度矩阵的正定性。此外,我们得到一个先验的间隙度量误差界。最后,我们表明,我们的方法基于正实平衡截断保持过阻尼二阶系统的结构。

英文摘要:

We introduce a model reduction approach for linear time-invariant second order systems based on positive real balanced truncation. Our method guarantees asymptotic stability and passivity of the reduced order model as well as the positive definiteness of the mass and stiffness matrices. Moreover, we receive an a priori gap metric error bound. Finally, we show that our method based on positive real balanced truncation preserves the structure of overdamped second order systems.
