前言随着微型计算机的迅速发展,越来越多的控制系统采用微型计算机来实现。控制工程人员将面临着这样一个局面,即要求他们尽快掌握微型计算机的应用,用更多的软件来取代他们曾经十分熟悉的单纯用硬件实现控制工程的方法。他们将发现用微型计算机十分灵活方便,一些用硬件很难做到的工作,而用微型计算机却是轻而易举的。至于微型计算机一机多 Introduction With the rapid development of microcomputers, more and more control systems are implemented by microcomputers. Control engineers are faced with the situation where they are required to get their hands on microcomputer applications as soon as possible and to use more software to replace their once-familiar hardware-only control engineering approach. They will find it very flexible and easy to use a microcomputer, some hard to do with the hardware, but using a microcomputer is easy. As for the microcomputer more than one machine
