摘要

本文介绍了在Matlab中对模拟器件最著名的模型降阶方法的实现和测试的实际结果。所提出的方法的主要特点是使用数学运算奇异值分解(svd)来实现。本文给出了线性系统模型降阶方法、带一组端点的线性系统模型降阶方法和分段线性逼近的非线性系统模型降阶方法的应用实例。本文定义了器件的建模,器件包含具有分布参数的元件。采用Simulink对设备进行描述,开发模块采用Matlab进行MOR。

Macromodeling of electronic circuits based on model order reduction
This paper presents practical results of realization and testing of the most famous approaches of model order reduction (MOR) for analog devices in Matlab. The key feature of presented approaches is their realization using mathematical operation singular value decomposition (svd). This paper includes examples of applying methods of model order reduction of linear systems, model order reduction of linear systems with a set of terminals, and model order reduction of nonlinear systems through piecewise-liner approximation. Devices, whose modeling is defined in this paper, contain elements with distributed parameters. Simulink was used to describe devices, developed modules Matlab were used for MOR.
