在生产过程控制中还大量存在着单输入单输出调节系统,它们在一定精度范围内可以用线性定常微分方程来描述.分析、设计这种类型的调节系统最常用的方法是经典调节理论中的微分方程法、根轨迹法及频率响应法.由于用手算时工作量太大、往往在工程设计中很少进行计算.然而,应用数字电子计算机来进行这些工作将是十分方便和迅速.本文介绍了电子计算机用分步法计算具有纯滞后的微分方程方法;用牛顿-雷森方法搜索根轨迹方法及计算系统的频率响应的方法.文中并列举了在DJS-21机上计算的一些算例.
There are also many single-input and single-output regulation systems in the production process control, which can be described by linear steady-state differential equations within a certain range of accuracy.The most commonly used method to analyze and design this type of regulation system is the classical regulation theory Differential equation method, root locus method and frequency response method are often used in engineering design because of the heavy workload, but it is very convenient and rapid to use digital electronic computer to do these tasks. This paper introduces a method of calculating differential equations with dead-hysteresis by computerized step-by-step method, a method of searching for root locus by Newton-Reynolds method, and a method of calculating the frequency response of the system.The article also lists some examples calculated on DJS-21 .
