【摘要】 为了解决控制器算法本身没有考虑的问题,过程对象的时变、强干扰以及过程控制中的突发事件与故障,采用控制器监督级进行有效的处理,以提升控制器的连续运行时间和稳定性。简述了控制器监督级的由来,归纳了它的主要任务,介绍了模块化的构造与设计方法。最后给出一个设计实例,针对锅炉主蒸汽温度控制回路,使用基于专家规则的方法设计了一个控制器智能监督级。应用结果证明了控制器智能监督级的有效性。更多还原

【Abstract】 Time-variant characteristic and strong disturbances as well as occasional failure are rarely taken into account by control algorithms. The supervisory shell for controllers can deal with these problems,increase operating-time and stability of the controllers.The origin of the su- pervisory shell for controllers are generalized, its main task is summed up,the modular structure and design method of the supervisory shell is introduced. Finally, an intelligent supervisory shell is designed for the controller of the main-steam temperature of boiler by using rule-based method. The application shows efficiency of the intelligent supervisory shell for controllers.更多还原
