摘要
液位控制是科研工作者研究控制理论的一种科研平台。上述系统具有观察方便、测量灵活、直观等诸多优点,能够实现各种控制方法的研究。现以浙大中控CS4000过程控制装置中的双容水箱液位作为被控对象,利用实验测定法建立双容水箱液位控制系统模型,分别设计了三种控制器:PID控制器、模糊控制器和模糊控制与PID结合控制器。在MATLAB中对以上三种控制方法进行SIMULINK仿真,对结果做分析与比较。最后借助于集散控制系统平台实现对所建立的双容水箱液位系统进行组态与调试。结果证实,模糊控制与PID结合方法和模糊控制效果均优于传统PID控制。
Liquid level control is a scientific research platform for researchers to study control theory.To achieve a variety of control methods of research,this system has many advantages,such as convenient observation,flexible measurement,intuitive,etc..CS4000 process control device in double-tank water level was as the controlled object in this paper.The double-tank water level control system model was established by using the experimental method.Three controllers were designed,that is,PID controller,fuzzy controller and fuzzy control and PID combined control-ler.The SIMULINK simulation of the above three control methods was carried out based on MATLAB,and the results were analyzed and compared.Finally,the configuration and debugging of the double-tank water level system estab-lished in this paper was realized by means of the distributed control system platform.The results confirm that the fuzzy control and PID combination method and fuzzy control effect are better than the traditional PID control.
