[Abstract]:With the rapid development of science and technology, especially the power electronics technology, computer control technology and microelectronics technology has made great progress, permanent magnet synchronous motor (PMSM) has gradually become the mainstream of AC servo system. Permanent magnet synchronous motor (PMSM) has been widely used in daily life, numerical control technology, aerospace and other fields because of its advantages of light weight, high performance and small size. Therefore, the study of PMSM control strategy is of great practical significance. Firstly, this paper introduces the development of PMSM in AC servo system, the mathematical model of PMSM and the principle of vector control. Then the principle of voltage space vector pulse width modulation control is introduced. Secondly, the modeling and simulation of PMSM AC servo system based on SVPWM in MATLAB / Simulink environment is carried out. Through simulation, the correctness of SVPWM control theory is verified, which lays the foundation for hardware design. Finally, on the basis of theoretical research and simulation analysis, the design of system software and hardware is completed. Hardware: with TMS320F2812 DSP as the core, the digital AC servo control system of permanent magnet motor is designed, including the main circuit, driving circuit and other circuits. Software: using C language and assembly language programming method, using CCS2000 integrated development environment and simulator to debug the program, complete the software design.
