A Dynamic Hunting Optimalizing Controller

本文阐述一种动态搜索的极值调节器的基本原理和设计方法,该调节器适用于具有很大的惯性的控制系统中,如果该系统的输出线性部分可以近似地用具有大时间常数或纯时延的一阶系统表示,其传递函数为K/1+TS或Ke^(-sτ)/(1+TS)。文中还较详细讨论系统的动态输出与逻辑电路策动输入之间的关系。该文还介绍了设计的极值调节器和系统模型及实验结果。

In this paper, the fundamental principle and the design method of an optimalizing controller with dynamic hunting is explained in accordance withthe control theory. This controller can be used in process control system. In this con-trol system, there are large inertial and other dynamic effects. If the output lineargroup of the system is approximately 6 【pressed in a first-order system with largetime constant T or time dely τ, which can be written as transfer function K/(1+TS) or Ke^(?) (1+TS). Moreover, relation between input drive reversal of logic cir-cuit and dynamic output of the system is discussed in detail. The calculating for-mulas for the drive reversal of logic circuit are given to the different transferfunction and they are proved correctly by tests. In accordance with the layout men-tioned above a controller and a model of system has been designed and made out. Meantime, some special tests have been carried on and the results showed that theperformance of the controller satisfied the chnical requirments in design and it may search the optimum point rapidly and keep the system operates near the point.
