SIMULINK实现QAM,来自韩国一本教材。(SIMULINK realize QAM, a teaching materials from South Korea.)

以Matlab软件为平台,研究基于模型的嵌入式系统的开发方法。以转差率控制异步电动机矢量控制系统为开发对象,重点研究了基于模型设计的关键技术,通过实验对这些技术进行了验证。将设计成果应用在异步电动机的控制当中,并取得与研究模型一致的控制效果,证明了基于模型的嵌入式系统设计的优越性。(Matlab software as a platform to study the model-based embedded systems development methodology. To slip controlled induction motor vector control system for the development of the object, focusing on the key technology of model-based design through experimental validation of these technologies. The design results with asynchronous motor control them, and made consistent with the control effect of the model, that model-based embedded system design advantages.)
