锅炉汽包水位模糊控制的应用研究
|
摘要
在分析常用锅炉汽包水位控制方式存在问题的基础上提出了双输入 -单输出汽包水位模糊控制系统。阐述了系统的工作原理以及模糊控制规则表和控制查询表的建立方法。最后给出系统结构图和程序流程简图 ,并将模糊控制运行曲线与前馈 -反馈控制运行曲线进行了比较。
On the basis of analysis of conventional drum water level control mode for boiler and existing problems, a dual inputs single output fuzzy water level control system is stated. The operational principle, and the establishing method of fuzzy control regulation table and control interrogation table are described. The diagram of system structure and the simplified program flowchart are given. In addition, the operational curves of both fuzzy control and feedforward feedback control are compared.
