多变量控制方法的分布式计算机控制系统

Distributed Computer Control System of Multiple Variable Control Method

介绍了一种具有多变量控制的分布式计算机控制系统的系统结构、硬件及软件设计．根据分散控制集中管理的原则，该系统采用过程控制机、ＣＲＴ操作站及上位机三层结构．在硬件及软件设计上均采用模块化方法，系统各部分之间由树状通讯网连接．过程控制机和ＣＲＴ操作站分别由高性能的ＳＴＤ总线控制机和２８６型操作站完成．该系统已应用于纺织、吹塑、采油等系统的控制，取得了令人满意的结果．

In this paper, the System Structure, hardware and software deign of distributed computercontrol system using an advanCed multiple variable control method are introduced. Acording to theprinciple of concentrated management and diStributed control,this System consists of a process controller,CRT an operating station and a main competer. The modeling method is used for hardware andsoftwaredsign, The sections of the system are connected through tree-shaped communication nets.The process controller and CRT operating station are respectively realized through high-performenceSTD bus controller and a 286 operating station. This system has been used for the control of such systems as spinning,extracting Oil and so on, with satisfactory results.
