摘要
文章对绘制开环系统极坐标图进行了深入研究 ,给出了极坐标图起始渐近线的判据 ,指出开环系统只有 1型系统才有起始渐近线。另外 ,还给出了极坐标图极值点判据和它的计算方法 ,这是由于极值点对于确定曲线形状很重要 。
In this paper, the method of plotting polar diagram of open loop systems is studied. The original asymptote criterion of polar diagram is improved, and it is pointed out that only one type system has original asymptote in the open loop systems.The crest volume criterions of polar diagram and the calculation method of crest volume are advanced. The crest volume is very important to the finality of diagram forms, but previous method of plotting polar diagram lacks of the crest volume calculation.
