模型降阶技术在自动控制系统中的应用研究
摘要
模型降阶是在某种情况下将一个较大系统转化为一个近似的较小系统的过程,以便降低大型复杂系统的理论分析难度和减少数据运算量.对于现代大型或复杂系统,由于其高维数或复杂性,直接进行分析相对困难或数值模拟耗时过长,甚至对某些问题无法模拟.在这样的背景下,对模型的规模或阶数进行有效的降阶处理就显得尤为重要了.
MATLAB 是美国MathWorks公司出品的商业数学软件,用于算法开发、数据可视化、数据分析以及数值计算的高级技术计算语言和交互式环境,主要包括MATLAB和Simulink两大部分.
本文研究了Routh近似降阶法和Pade逼近降阶法,分析了这两种降阶法的意义、原理与方法,并用matlab编写上述两种方法的程序.运用matlab gui编写了一个简单的人机交互软件,实现了Routh近似降阶法和Pade逼近降阶法,输入参数后,点击即可快速降阶.

Model reduction technique in automatic control systemAbstractModel reduction is in some cases a larger system into an approximation of the smaller system process, in order to reduce the large complex system theory analysis of difficulty and reduce the amount of data operation. For modern large or complex system, because of its high dimension or complexity, direct analysis of relative difficulty or numerical simulation time is too long, even on some problems can not be simulated. In this context, the model with a scale or order for effective reduction treatment is particularly important.MATLAB is the United States of America MathWorks company business mathematics software, used in algorithm development, data visualization, data analysis and numerical calculation of senior technical computing language and interactive environment, including MATLAB and Simulink of two parts.This paper studies the Routh approximate reduction method and Pade approximation order reduction method, analyzes the two reduction significance, principle and method, and Matlab prepared with the above two methods procedures. Use Matlab GUI prepared a simple human-computer interaction software, realized Routh approximate reduction method and Pade approximation order reduction method, input parameters, click quick reduction.
