摘要
本文在已有文献基础上,提出最佳和次佳函数概念,并给出寻找方法。这些结果既可以用来作理论分析,又可以用来实际确定绝对稳定角域中的K值,与传统的频率方法相比,优点是能较方便地给出相应的型V函数。
In this paper, the concepts of optimal and sub-optimal Luric function arc presented,based on known works. The methods looking for one arc given,respectively. Those results can be used both to analyze absolute stability of a control systems,and to determine K-value of sector region for absolute stability in practice. Our method is better than traditional frequensy method in constructing Luric funtions.
