自校正控制炉温的研究

A STUDY ON SELF—TUNING CONTROL FOR THE TEMPERATURE OF THE FURNACE

本文提出自校正控制炉温的硬件配置、软件及实验等问题,其中包括如何结合实际解决数据采集、参数估计、模型化及自校正实时控制等一系列软件开发的新问题.通过多次现场实验结果表明,自校正控温效果优于 PID,特别是自校正控制易于用微机实现,具有推广应用价值.

This paper discusses problems about the realization of software and the disposition of hardware of the self—tuning control over the temperature in the furnace and the experi- ments.Specifically,the problems include the following aspects:data collection,identifica- tion,emulation and a series of specific problems in software development of self—tuning, real-time control. Through the tho kinds of practical experiments of self-tuning control and PID con- trol,the experiment results show that the stable performance of controlling temperature by self-tuning control is better than that by PID control.Furthermore,the self-tuning con- trol is easy to realise on a microcomputer and doesn't often need manually adjusting parameters.Thus,the self-tuning control has great value of wide applications.
