Abstract

This paper proposes a quick and smooth speed servo system considering acceleration torque and total harmonic distortion (THD) for AC servo motor, which realizes both a quick speed response in transient state and a small value of THD in steady state. The proposed system has a new space voltage vector modulation (SVM) inverter, which is the mixed voltage limitation method of SVM. The proposed method achieves the fine performance in the experimental results of surface permanent magnet synchronous motor (SPM motor).
