本文介绍一种适用于多种工业对象的通用数字控制器。这种控制器不仅提供了通常的积分分离P、I、D控制算法,而且还可以用于具有大惯性、大纯滞后的系统及回路系统。此外适应快速性、高控制精度等诸方面的控制要求。该控制器的软件是在以Z-80CPU为核心的TK-80工业控制机上开发与研制的。TK-80机配有完备的外围通道,可以方便地与生产现场连接,再配上本文介绍的数字控制器后,大大提高了它的控制性能。根据我们在400万大卡/时热媒间接加热炉最优燃烧控制系统样机上的应用结果表明:该控制器使用灵活、参数调整方便、适应性强,对于具有大纯滞后的燃烧系统显示出良好的控制特性。此外该控制器还具有微机故障的自诊断功能,从而提高了微机系统整机运行的可靠性。
This article describes a versatile digital controller for a variety of industrial applications. This controller not only provides the usual integral separation P, I, D control algorithm, but also can be used in systems with large inertia and large net delay and loop system. In addition to meet the rapidity, high control accuracy and other aspects of the control requirements. The controller software is developed and developed on the TK-80 industrial control machine with Z-80CPU as the core. TK-80 machine with a complete peripheral channel, you can easily connect with the production site, coupled with the digital controller described in this article, greatly improving its control performance. According to our application in the prototype of the optimal combustion control system of indirect heating furnace with 4 million kcal / h, the results show that the controller is flexible to use, easy to adjust the parameters and adaptable. For the combustion system with large hysteresis, Good control characteristics. In addition, the controller also has a self-diagnostic function of the microcomputer fault, thus improving the reliability of the whole system of the microcomputer system.
