本文用修正无变换法分析研究了用于大纯滞后过程的采样控制系统,在肯定这种控制系统对大纯滞后过程是很有效的同时,讨论了调节器整定参数的计算方法和系统的若干实施要点。由于这种控制方法在国内外均有了一定的实践基础,本文的工作只是企图在理论上有所进展,使它成为可以理解、可以定量计算的一种控制方案,以作为进一步研究这种具有一定发展前途的控制方法的新起点。文中所推导的离散二阶系统的计算公式也可用来解决其他离散控制系统的有关问题。
In this paper, the modified no-change method is used to analyze and study the sampling control system used in the large-hysteresis process. While this control system is proved to be effective for the large-hysteresis process, the calculation methods and system of the tuning parameters are discussed Implementation points. Because this control method has a certain practical base both at home and abroad, the work in this paper is only an attempt to make some progress in theory, making it a understandable and quantifiable control scheme as a further study of this A certain new starting point for the development of control methods. The calculation formula of discrete second-order system deduced in this paper can also be used to solve the related problems of other discrete control systems.
