Study on vector control system of asynchronous motor based on simplified three-level SVPWM

摘要

This paper described a simplified three-level SVPWM algorithm, had a detail theoretical analysis on a full order closed loop rotor flux observer. The vector control of the asynchronous motor without speed sensor was conducted with the application of the identification speed of the director comprehensive method base on the status equation. An experimental platform was set up with DSP F2812 as the main controller in the Lab to verify the excellent performance of the algorithm.
