本文介绍作者根据D.W.Clarke等提出的自校正控制器的思想,针对受控对象为一低温生物保存降温设备的具体情况,以TP-801单板微型计算机为主体所成功实现的对该设备降温及保温过程的自校正控制。文章除对控制装置的原理、硬件构成及软件编制作简要介绍外,还讨论了其中某些参数的选取及与系统调试有关的一些问题,并记述了在设备热容量变化、环境温度变化以及骤加扰动的情况下与PID数字式调节器的对比试验结果。 This article describes the author according to DWClarke and other self-tuning controller proposed the idea for the controlled object is a low-temperature biological preservation cooling equipment for the specific circumstances to TP-801 single-board microcomputer as the main body of the successful cooling of the device and Self-correcting control of heat preservation process. In addition to a brief introduction to the principle, hardware configuration and software compilation of the control device, the paper also discusses the selection of some of these parameters and some problems related to system debugging. The article also describes the changes in the equipment thermal capacity, ambient temperature and sudden increase Contrast test results with PID digital regulator in case of disturbance.
