摘要
分析了永磁同步电机系统的研究现状,设计了一种以TMS320F2407为控制核心的变频调速系统。首先对系统的硬件及软件结构进行介绍,接下来分析了永磁同步电机磁场定向矢量控制的工作原理及控制方法,并对永磁同步电机伺服系统进行了数学建模。在此基础上设计了PI控制器,将该控制器用于永磁同步电机变频调速系统。最后用MATLAB仿真工具进行了仿真,仿真结果表明:对于具有非线性、耦合性强及参数漂移较大等特点的永磁同步电机来说,系统既可适应对象参数的变化,又能很好的消除稳态误差,获得了较高的控制精度。
This paper analyzed the present research situation of the permanent magnet synchronous motor system,and designed the variable frequency regulation speed system using TMS320F2407 as the control core.Firstly,the structure of hardware and software of the system were introduced.Then the working principle and control method of the PMSM vector control were analyzed and the mathematical modeling of permanent magnet synchronous motor servo system was built.On this basis the PI controller was designed and used in permanent magnet synchronous motor variable frequency speed control system.Finally the system was simulated using the MATLAB simulation tool,and the simulation results show that the system not only can adapt to the changes of object parameters,but also eliminate the steady state error and obtain a higher control precision for the permanent magnet synchronous motor with the characteristics of nonlinear,strong coupling and the parameters excursion.
