This paper proposes a speed servo system based on a space voltage vector modulation (SVM) inverter with the mixed voltage limitation method considering acceleration torque and voltage saturation for AC servo motor. The servo system realizes both a quick speed response and a small value of total harmonic distortion (THD) in steady state. The experimental results of surface permanent magnet synchronous motor drive confirm that the proposed method achieves the fine speed and current performance.
