摘要
通过大量仿真 ,对按照模型降阶的图解法和矩法 ( I) (《西北轻工业学院学报》2 0 0 1年第 4期 )中给出的图解降阶法和矩降阶法所得的低阶模型的逼近能力进行了详尽的分析和比较 ,展示了这两类模型降阶方法的优越性。仿真以 Matlab为仿真工具进行 ,仿真内容涉及开环响应比较、Nyquist曲线比较和闭环响应比较。
This paper is the continuous part of reference 〔1〕.A detailed analysis and comparison among the approximating abilities of the low models resulted from the proposed two order reduction methods in reference 〔1〕 is done by a large number of simulations, by which the advantages of these two methods are shown. Simulations are done via Matlab, which involve in comparisons of open loop response, Nyquist curves and close loop response Several suggestions are also given in the end.
