一、微处理机和控制器随着微处理机日益广泛地用于工业生产装置,如何用一个微处理机系统组成一个智能化的数字控制器来取代一个常规的 PID 模拟控制器?便十分自然地被使用者提出。这种智能化数字控制器不仅具有模拟控制器所无法比拟的优越性,而且它是构成集散型实时计算机控制系统的最基本单元之一。
Microprocessors and Controllers As microprocessors are increasingly used in industrial production installations, it is quite natural how to replace a conventional PID analog controller with a microprocessor-based system consisting of an intelligent digital controller To be users. This intelligent digital controller not only has the superiority of analog controller, but also it is one of the most basic units that form the distributed real-time computer control system.
