摘要

本文提出了一种描述新型微推进装置的线性热电模型的自动降阶方法。降低模型阶数是实现易于评估，但准确的设备宏观模型的必要条件。我们给出了全有限元模型和描述器件瞬态热电行为的不同降阶模型的数值模拟结果。在Guyan之后，显示了基于arnoldi算法的模型降阶优于商业上可用的降阶建模。

Automatic order reduction of thermo-electric models for MEMS: Arnoldi versus Guyan

In this paper we present an automatic order reduction of a linear thermo-electric model describing a novel type of micropropulsion device. Model order reduction is essential to achieve easily to evaluate, yet accurate macromodel of the device. We present numerical simulation results of the full finite element model and the different reduced order models that describe the transient thermo-electric behaviour of the device. The advantages of an Arnoldi-algorithm-based model order reduction over a commercially available reduced order modeling after Guyan are shown.
