基于matlab的永磁同步电机调速系统的仿真

下载后可任意编辑摘 要本文首先介绍了永磁同步电机的国内外进展状况，然后介绍了永磁同步电机的结构及原理，接着建立了永磁同步电机的数学模型，并在此基础上用 MATLAB进行了仿真，最后进行了仿真及仿真结果的分析。永磁同步电机是具有非线性、强耦合性、时变性的系统，在运行过程中会受到负载扰动等多因素影响。以往讨论永磁同步电机的做法是在硬件上搭建一个平台进行模拟，但是这样在做实验中难免会造成一些损失，而且硬件上的反馈会比较长讨论周期长。目前在国内外关于永磁同步电机调速系统的讨论现状上来讲，基于 MATLAB 环境下仿真模型的构建下进行讨论，这可极大的缩短讨论周期和讨论成本。在利用 MATLAB 仿真模型讨论永磁同步电机时，我们可以把那些扰动因数做成模拟信号给予模型，这样可以准确的定性分析实验得出结论。关键字：永磁同步电机，空间矢量调制，MATLAB 仿真，数学模型。ABSTRACTIn the first, this paper introduces the domestic and international development status of Permanent Magnet Synchronous Motor(PMSM), gives a explanation about its basictheory, structure. Then it builds a mathematical model, and uses MATLAB to simulate that model.The PMSM is a nonlinear, strong-coupling and time-varying system, so in the operation process, it will be influenced by many factors such asload disturbance. 下载后可任意编辑Therere, it is necessary to take action when researching the control method of PMSM. The former research method is setting up a platform on hardware to perform experimensbut it is undesirable, because it often cause some loss, and the feedback cycle is longer than research cycle. As fordomestic and international current situation on the research of PMSM, it is obvious that researching under the simulation model created by MATLAB could greatly reduce the cost and cycle of researchment. When using MATLAB to build simulation model on the research of PMSM, we can transform these disturbance factors into analog signal, making a qualitative analysi...
