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．
This paper introduces the system structure, hardware and software design of a distributed computer control system with multivariable control. According to the principle of centralized management of decentralized control, this system adopts three-layer structure of process control machine, CRT operating station and host computer. In the hardware and software design are modular approach, the various parts of the system by the tree communications network connection. The process controller and CRT operator station are respectively completed by a high-performance STD bus controller and a Type 286 operator station. The system has been used in textile, blow molding, oil production and other systems control, and achieved satisfactory results.
