摘要
实际控制系统中复杂的高阶系统简化一直是控制系统中的重点和难点。本文主要利用数学知识讨论了一种不保留极点法简化方法,与传统的保留极点法相比:精度更高,更接近于原系统的频率响应。文章最后应用MATLAB进行分析,比较了两种方法性能结果。
It is quite useful to study complex system with high - order transfer functions by using lower -order approximate models, This paper considers a new method to reducing the order of a system transfer function comparing the traditional method. The traditional method is to delete a certain insignificant pole of a transfer function. This new approach is not to retain the dominant poles of the original system. Finally, use MATLAB to compare the approximate model to the actual model.
