摘　　要：提出一种基于机理模型的实验室装置虚拟仿真软件开发方法。以过程控制实验装置A3000水箱系统为仿真对象,首先用机理分析法建立其数学模型,并采用实验测试法辨识模型中的未知参数,然后利用LabVIEW软件开发工艺流程界面、PID控制器界面和相应的后台程序框图,从而建立该实验装置的虚拟仿真软件。该软件能够较好模拟真实实验装置的特性变化,有助于学生熟悉工艺流程和控制方案,有助于学生深入讨论实验过程,为进一步开展创新性实验提供平台支撑。This paper proposes a virtual simulation software development method based on mechanism model for the real laboratory device. One process control experiment device of A3000 water tank system is used as the simulation objective.Firstly,its mathematical models are built using the mechanism analysis and the unknown model parameters are identified by the experimental testing. Then Lab VIEW software is applied to develop the process flow interface,PID controller interface and the background program block diagram. Lastly the virtual simulation software is built for the laboratory device. This software can simulate the real device characteristics well. It is useful for students to learn the process flow and control strategy and discuss the experiment principle deeply. The method provide a platform for the innovative experiment.
