Abstract: An asynchronous motor vector control system based on modulation of SVPWM was proposed. The motor torque was decoupled directly by the way of vector control with doubleloop based on the modulation of voltage space vector and the ideal control performance was achieved. The simulation indicates that the mentioned technique has a low computational complexity which can be easily carried out with a good robustness, and has a sense of reality.
Key words: voltage space vector pulsewidth modulation (SVPWM); decoupling; vector control; robustness
