摘要
为了模拟工业锅炉液位过程控制,以水箱过程控制实验装置为基础进行了液位控制的实验研究。首先提出了基于演算子理论的右互质分解方法实现非线性控制系统的设计;接着以PCL-812PG数据采集卡为基础进行了数据采集与驱动设计;然后利用设计好的控制器在Visual C++开发环境下对该液位系统进行了实验研究;实验中液位设定值为300mm,结果显示液位控制系统上升时间小于260s,系统超调低于5%,满足要求的性能指标;实验结果表明了控制系统设计的有效性。
A twin-tank based experimental control system is set up in order to simulate a water level process control system of an industrial boiler,and experimental study is discussed for the water level process control.Firstly,Operator-based robust right coprime factorization algorithm is introduced for the system;After that,data acquisition and driven are realized by using PCL-812 PG card.Also,under Microsoft Visual C++ developing environment,the designed right coprime factorization algorithm is applied to the control system.The monitoring image display the response time is fast,has small overshoot,the comprehensive index is good.The experimental results are given to show the effectiveness of the built control system.
