纯滞后系统完全补偿,对系统品质的改善已为自动控制工作者所熟知。而由实验或分析得到的数学模型,只是实际模型的一类近似。实际过程模型的“真正模型”是无法得到的。从这意义上来说炼油、化工等生产过程的纯滞后所谓完全补偿,也只能足一种不完全补偿。因此探讨、认识不完全补偿是必要的。本文主要以Smith补偿控制的结构进行不完全补偿研究,给出了一些高阶工业系统补偿控制近似补偿实例。并给出了用DJM310Ⅱ-IBMPC/XT混合计算机系统进行仿真的结果。
The purely lagged system is fully compensated and the improvement on the quality of the system is already well-known to the automatic control engineer. The mathematical model obtained by experiment or analysis is only a kind of approximation of the actual model. The “real model” of the actual process model is not available. In this sense, the so-called complete lag of pure lag in the refining, chemical and other production processes can only provide enough compensation. Therefore, to explore and understand incomplete compensation is necessary. In this paper, the structure of Smith compensation control is mainly used to study the incomplete compensation, and some compensation compensation examples of some high-level industrial systems are given. The results of simulation with DJM310Ⅱ-IBMPC / XT hybrid computer system are given.
