Abstract

Vector control technology is regard as a kind of controlling manner of AC asynchronous motor, and it is already become the first method of the high-performance variable-frequency speed regulating system. Compared with SPWM, SVPWM (space vector pulse width modulation) has been used widely because it has better performance. This paper introduced the basic principle of voltage SVPWM and vector control. A full-digital solution with TMS320LF2407 using simplified SVPWM control method is presented. Through the experiment of controlling to a practical motor, the resulted shows that this method is feasible, the controlling system has better dynamic and static performances and controlling effect, it would have a prospect widely used.
