[Abstract]:With the increasing environmental pollution and energy crisis in the world, people pay more and more attention to the development of electric vehicles. In recent years, many automobile manufacturers continue to introduce new electric vehicles. Our country has invested a lot of R & D and production in the field of electric vehicle, obtained many independent intellectual property rights, and promoted the promotion of new energy of automobile. The core component of electric vehicle is motor drive system. PMSM has the advantages of small size, high control precision, high torque density, high power factor, wide speed range and so on. At present, it has been widely used in electric vehicle drive system. In order to give full play to the excellent performance of permanent magnet synchronous motor (PMSM), Good motor drive and control technology is needed. This subject takes 50kW built-in permanent magnet synchronous motor (PMSM) of Suzhou Hexin Electric Company as the controlled object. The main contents of this paper are as follows: firstly, the mathematical model of permanent magnet synchronous motor (PMSM) is established, and the vector control principle of PMSM is analyzed. In addition, the space vector pulse width modulation, which is an important part of vector control, is proposed to realize the maximum torque / current ratio and weak magnetic field control of input expected torque. The hardware circuit of the PMSM driving controller is designed, which includes the main control board and the drive board. The main control board is the control core of the system, which realizes the signal acquisition and data processing. The driver board receives the control signal from the main control board, amplifies the SVPWM signal, controls the IGBT turn on / off, realizes the control of the motor. The software is designed in the CCS3.3 environment of TMS320F28335. The whole digital vector control algorithm is realized based on C speech. Finally, the motor and its driving controller are tested and verified based on the motor control test platform. The experimental results show that the PMSM drive controller designed in this paper has the characteristics of high reliability and wide speed regulation.
