| 摘 要： | 针对工业二甲基甲酰氨（DMF）回收装置，设计了以专家推理思想为基础的区域专家协调控制系统（RECCS），它以西门子S7-300PLC组成的集散控制系统为基础，改进原有的回收工艺，增加智能控制器，能根据系统中的采集变量判断各个区域所处状态, 并且总体考虑了各个区域的参数关联问题。该控制系统根据专家知识协调控制区域内的PID控制器，能够实现DMF回收过程全自动监测与控制,通过建模仿真和现场的运行证明了专家协调控制系统的有效性，可以很方便的与现有DCS集成为智能控制系统，具有广泛的发展前景。

| Abstract: | Aiming at an industrial DMF recovery plant, a kind of region expert coordination control system (RECCS) based on expert inference mechanism was proposed. With an S7-300 PLC based distributed control architecture, the expert control system can identify the operation states of regions from coupling data of the plant. The regional PID controllers were coordinated with the expert coordinating rules to realize plant-wide automation of the DMF recovery process. Simulation results on distillation models illustrated the effectiveness of the coordination control system. Easily integrated with DCS，the proposed expert region coordination control technique could be widely used in industrial applications. |
