【摘要】：随着逆变器的发展,逆变器的控制越来越多的使用DSP等数字控制器来实现。功能越来越多的逆变器导致数字控制器的程序编写困难增加,如何加快控制代码的开发进度并降低控制代码的开发难度是当前急需解决的问题。而控制算法的开发中常用的MATLAB/Simulink仿真运算软件已经非常成熟,但Simulink模型搭建的算法模型只针对纯软件环境的仿真,无法直接将模型应用于实际的DSP等数字控制上。控制算法经过Simulink模型验证后仍需手动编写控制代码,如何加快算法从模型验证到实际应用的进度仍是需要解决的问题。本文针对逆变器开发中DSP等数字控制器的代码开发任务繁重且Simulink仿真模型无法直接应用于实际数字控制器中的问题,提出基于Simulink模型自动DSP代码生成的逆变器的研制的课题。使用Simulink搭建逆变器控制算法的完整模型,通过安装相应软件以及对模型进行参数设置,将Simulink算法模型直接生成DSP可执行的代码工程文件,实现从算法模型生成控制代码。极大的增加了Simulink模型的实际应用价值,加快了逆变器中数字控制器的代码开发进度,降低了逆变器控制代码开发的难度,具有较大的实际应用价值。本文进行了基于Simulink模型自动DSP代码的三相逆变器研制,使用FOC控制三相异步电动机。首先搭建了基于Simulink模型进行代码开发需要的软件平台,然后搭建了基于Simulink模型的FOC控制算法且生成了 FOC算法的自动DSP代码文件。针对模型设计了必要的硬件电路,最后在完整的实验平台上验证了本文的研究内容,印证了本课题的可行性和实用性。
[Abstract]:With the development of inverter, more and more digital controllers such as DSP are used to control the inverter. How to speed up the development of the control code and reduce the difficulty of the development of the control code is a problem that needs to be solved. However, the MATLAB/Simulink simulation software commonly used in the development of the control algorithm is very mature. However, the algorithm model built by Simulink model is only aimed at the simulation of pure software environment, and can not be directly applied to the actual digital control such as DSP. The control algorithm still needs to be written manually after the verification of the Simulink model. How to speed up the algorithm from model verification to practical application is still a problem to be solved. The task of code development of digital controller such as DSP in inverter development is heavy and the Simulink simulation model can not be directly applied to practice. Problems in digital controllers, The research and development of inverter based on Simulink model automatic DSP code generation is put forward. The complete model of inverter control algorithm is built by using Simulink, and the corresponding software is installed and the parameters of the model are set up. The Simulink algorithm model is directly generated from the DSP executable code engineering file, and the control code is generated from the algorithm model. The practical application value of the Simulink model is greatly increased, and the code development progress of the digital controller in the inverter is accelerated. It reduces the difficulty of inverter control code development and has great practical application value. In this paper, a three-phase inverter based on Simulink model automatic DSP code is developed. The three-phase asynchronous motor is controlled by FOC. Firstly, the software platform based on Simulink model for code development is built. Then the FOC control algorithm based on Simulink model is built and the automatic DSP code file of FOC algorithm is generated. The necessary hardware circuit is designed for the model. Finally, the research content of this paper is verified on the complete experimental platform. It proves the feasibility and practicability of this subject.
