毕业论文-基于统一建模语言的同步电机建模及仿真.doc

摘 要 目前， 随着计算机技术和模拟建模技术的发展，数学建模与仿真在产品设计中的作用越来越重要，已经成为测试和分析产品技术性能的一项重要手段。然而，现在产品的复杂程度逐渐提高，往往涉及机械、控制、电子、和软件等多学科领域,其每个部件、子系统都可能是由各个学科领域的零部件组成, 虽然各个学科领域都有比较成熟的仿真软件,但大部分仿真软件仅适用于本学科领域,并在模型表述中采用自己专门的格式,而复杂产品的整体性能需要多个领域仿真软件的协同仿真,需要在多个仿真软件间进行大量的数据交换,并进行系统层面上的建模,单领域仿真建模工具很难满足要求。因此要设计多领域建模与仿真平台，以满足当今产品生产的需要。 在本论文中，通过对多领域建模语言Modelica在数字电路中的应用以及多领域物理系统仿真平台Dymola系统的应用的介绍，让我们初步了解了多领域建模与仿真在当今产品设计中的应用。该论文主要包含以下的几个主要部分：首先介绍当今多领域建模仿真的发展状况。其次，介绍了有关电路设计和仿真的一些有关软件和平台，以及Modelica语言和Dymola仿真平台。接着，介绍了同步电机工作原理以及它的数学模型。最后，讲述如何利用Modelica语言和Dymola仿真平台建立同步电机仿真模型，以及对它进行分析测试。 本论文对课题的设计方法以及所利用的理论知识进行了详细的阐述，并对多领域建模语言Modelica以及仿真平台Dymola系统进行了介绍。 关键字：同步电机建模仿真；同步电机动态响应；Modelica； Dymola系统。 Abstract At present, along with the computer technology and the simulation modelling technology development, mathematics modelling and the simulation is more and more important in the product design function,already became the test and an analysis product technical performance important method.However, now the product complex degree gradually enhances, often involves the machinery, the control, the electron, and software and soon the multi-disciplinary domain, its each part, the subsystem all possibly are is composed by each discipline domain spare part. Although each discipline domain has quite mature simulation softwares, however, most simulation softwares applie only to the areas of themselves, used their own special formats to illustrate the models, but complex products require multiple areas of the overall performance of simulation softwares co-simulation, and need a large number of data exchange among a number of simulation softwares,modeling on system level. single field of simulation modeling tools are very difficult to meet the requirements, therefore must design the multi- domains modelling and the simulation platform, meets now the product production needs. In this paper, through to multi- domains modelling language Modelica in the digital circuit application as well as the multi-domain
