摘　　要：针对间歇反应釜生产过程中存在的自动化控制水平相对落后、工人劳动强度大、控制精度低、主产率不理想等问题,提出了基于西门子PCS7的智能化自动控制系统。首先介绍了系统的总体设计方案,然后叙述了智能控制器的设计和硬件组成,最后就Mat-lab仿真和实际运行效果进行了分析总结。使用串级控制算法(外环使用模糊专家PID参数自整定系统控制温度,内环使用PID来抑制扰动)有效地解决了生产中存在的主要问题,为产品质量产量提供了有力的保障。Aiming at the problems existing in production process of intermittent stills, e. g. , poor level in automation, intensive labor of workers, control accuracy, and insufficient production efficiency, an intelligent automatic control system based on Siemens PCS7 is proposed. The general design scheme of the system is introduced first, then the design and hardware composition of intelligent controller is described in detail, and the simulation based on Matlab and practical operation effects are analyzed and summarized finally. The main problems existing in production have been effectively resolved by adopting cascade control algorithm （fuzzy expert PID self-tuning temperature control as the outer loop, and PID disturbance suppression as the inner loop）. The quality and yield of products are guaranteed.
