Abstract :
The paper introduces the basic principles of space vector pulse width modulation (SVPWM) and SVPWM algorithm. According to the permanent magnet synchronous motor (PMSM) servo system, basing on the analysis of PMSM mathematical model and the principle of vector control, it builds a permanent magnet synchronous motor vector control system simulation model and carries out the simulation analysis. According to the detection of permanent magnet synchronous motor rotor initial position, it brings out the tiny displacement type proposed detection method. The simulation result shows the feasibility, high reliability and effectiveness of control methods, so it has important significance in achieving high precision control of permanent magnet synchronous motor.
