控制对象及反馈环节的暂态特性可用S域的有理函数式表达的系统设计,国内外早有研究,提出许多设计方法。J.JBONGIONO和D.C.YOULA提出了一个准最佳设计程序,由此得出了一些基本结论。本文依据该文献中得出的基本结论,提出一个直接待定法。首先依据给定的控制对象和反馈环节及具体的设计指标:导出几个关系式定出闭环特征方程的阶数,定出控制器的分子、分母多项式的阶数,然后设一个系
The transient characteristics of the control object and the feedback link can be expressed by the rational function of the S-domain system design. Many studies have been made at home and abroad, and many design methods are proposed. J.JBONGIONO and D.C.YOULA proposed a quasi-optimal design procedure, which led to some basic conclusions. Based on the basic conclusions drawn in the literature, this article proposes a direct to be determined method. First of all, according to the given control object and feedback link and the specific design index, we derive several relations to determine the order of the closed-loop eigenvalue equation, set the order of numerator and denominator polynomial of the controller, and then set a system
