摘要/Abstract

摘要： 为提高自动控制相关课程的实验教学水平, 研制出一套四容水箱液位控制装置。该装置选用工业上常用的硬件设备, 软件部分设计了 Matlab / GUI(Graphical User Interface)操作界面, 可允许在 Matlab 中直接编程实现对系统的控制。建立了四容水箱系统的数学模型, 并利用阶跃响应法辨识系统的模型参数。针对四容水箱系统设计了分散内模控制器, 仿真环节采用 Matlab / Simulink 完成, 实现了四容水箱系统液位的跟踪控制。实验结果表明, 采用内模控制器的四容水箱系统, 当其中一个水箱的水位发生变化时, 对其他水箱的水位影响很小, 系统具有满意的控制效果。在自控等相关课程中, 该装置可以作为一种新的实验设备, 并具有较好的实验教学效果。

Abstract: In order to improve the experimental teaching of relevant courses in automatic control, the design of a four-tank system is presented. The hardware is composed of general industrial components, while a Matlab programming environment is used for the software to directly control the system. A graphical user interface is also adopted to provide an easy way to run the system. The four-tank system model is built, and its parameters are identified based on a step response experiment. Furthermore, a distributed internal mode controller is designed for the liquid tracking control of the four-tank system. The results show that the four-tank system, using the internal mode controller, has little effect on the water level of the other tank when the water level of one tank changes, and the system has a satisfactory control effect. This experiment could play an important role in the teaching of relevant courses in automatic control.

Key words: four-tank system, Matlab / graphical user interface ( GUI ) operation interface, internal model control, distributed control
