[Abstract]:In this paper, the modeling and control of permanent magnet synchronous motor (PMSM) is studied. The development and research background of permanent magnet synchronous motor are introduced. The structure of permanent magnet synchronous motor is analyzed in detail. The mathematical model of permanent magnet synchronous motor is built up in theory. Each parameter of the magnetic synchronous motor is quantified. In the control aspect, the common control mode of permanent magnet synchronous motor is summarized, and its advantages and disadvantages are compared. After that, the space vector control mode (SVPWM) is selected according to the different characteristics. In view of its control mode, this paper has carried out a theoretical deduction and introduced the vector of permanent magnet synchronous motor. On this basis, the control mode of space vector control is studied in detail. By introducing the concept of sector, basic vector, action time and so on, any vector is converted into the synthesis of the basic vector. By adding the inverter, the switch of the vector is converted to the switching of the bridge arm switch. The space vector control method is put forward, and the TI DSP chip is analyzed and the time sequence diagram is given. The simulation model of the permanent magnet synchronous motor and the space vector controller model are built through the MATLAB/Simulink module, and the space is found by the theoretical analysis and the computer simulation. The optimal parameters of the vector controller. Then, the hardware and software parts of the drive controller of the permanent magnet synchronous motor are designed independently. The monitor interface of the driver is designed by Visual Studio 2015 software, which can dynamically display the motor's detailed motion state. Finally, the controller is tested in the practical engineering application by putting the controller into the test. A simple adjustment for different applications can achieve good results, especially in a wheelbarrow, shuttle and other practical applications, and the practical performance of the controller is verified by the application results.
