生产中大部分液位控制系统的被控对象都可以看作是某种具有类似特征的蓄储液系统,它的建模研究具有重要的实际意义。以水箱系统的建模为例,研究常见的机理分析建模方法和基于模糊推理的新建模方法在蓄储液系统建模中的应用。通过设计系列的对比实验,借助计算机仿真与实物实验相结合的方法,对两种建模方法进行了系统的比较与分析,指出了两种建模方法各自的特点及其适用的对象。
A lot of level control systems can be seen as a kind of liquid storage vessel system,and it is practical to study the modeling methods for the system.In this paper,two modeling methods for this vessel system are illustrated by the example of a tank level control system,that are a novel fuzzy inference modeling method and a mechanical modeling method.A series of experiments are designed to analyze this two modeling methods,and based on the simulation result and practical experiments,the characteristics of these modeling methods are addressed and their applying field are clarified.
