Abstract :
In order to facilitate real-time computation of the digital signal processor (DSP), a simplified space vector pulse width modulation (S-SVPWM) is proposed in this paper. Through the establishment of a special coordinate system, the six sectors in the traditional space vector pulse width modulation are reduced to three, and the corresponding calculation becomes simple, which is more suitable for digital system. With MATLAB7.1/Simulink, a permanent magnet synchronous motor (PMSM) control system adopting S-SVPWM and the rotor field oriented control algorithm is set up. Simulation results rectify the effectiveness of the S-SVPWM algorithm, which provides the theory basis for practical applications.
