引言采矿研究院(MRDE)是英国煤炭局(NCB)从事采矿研究、开发和试验的中心。近年来,采矿研究院的主要研究课题之一是系统控制。这是测量、分析和操作的闭环过程。系统控制作为一个概念,当然不是新东西,传感、决策和动作,这样的过程也是人们习以为常的。只不过是将现代技术应用到闭环系统。测量仪表把电 Introduction The Mining Research Institute (MRDE) is the center of the British Coal Board (NCB) for mining research, development and testing. In recent years, one of the main research topics of the Mining Research Institute is system control. This is a closed-loop process of measurement, analysis and operation. System control as a concept, of course, is not something new, sensing, decision-making and action, this process is also used to people. It is simply applying modern technology to closed-loop systems.
