摘　　要：实验教学是实现素质教育和创新人才培养的重要教学环节。自动控制专业课程教学过程中,如自动控制原理,最优控制等,控制对象模型抽象,需借助建模工具讲解系统内涵与动态特性。通用建模工具模型抽象,物理含义不明确,而专业建模工具无法满足多领域建模需要。为了弥补上述实验教学模式的不足,介绍一种新型的、面向对象的多领域统一建模语言Modelica,并通过典型控制教学实例详述了其架构及实验的操作流程。试验结果证明,Modelica可以很好地反映多领域系统物理过程的变化,物理含义明确,模型易于维护,适用于多门自动控制类专业教学。In teaching process of automation control discipline,e.g.automation control theory,optimum control,the abstract model of control target needs modeling tools to explain or demonstrate system connotation and dynamic behaviors.General modeling tools yields to abstract model and vague physical meanings,while signal-domain modeling tools cannot model multi-domain objects.A practical temperature control system involves electrical and thermodynamics etc.,and tends to simulate the intermediate physical process,which makes both general and single-domain modeling tools unsuitable for the modeling task.To address the problem,a multi-domain physical modeling language,Modelica,is used to modeling a three-tank temperature-level system,including tanks,heater and controller etc.The model is simulated in Sim Forge environment.Results show that Modelica can well reflect the changes of physical process.The modeling process is simple and easy to maintain,when the obtained model has clear physical meaning.Modelica is suitable for multiple teaching propose in automation control discipline.
