碩士 === 國立臺灣海洋大學 === 電機工程學系 === 107 === In this thesis, predictive current controllers with discrete space-vector modulation for surface-mounted permanent magnet synchronous motors are proposed. The proposed controllers can apply three fixed-time voltage vectors in one sampling period, thus obtaining 37 composited voltage vectors. The proposed method is to improve the existing model-free current prediction methods and make detailed experimental comparisons with the model-based current prediction methods. The experimental platform is based on the TMS320F28379D microcontroller as the control core. Finally, the experimental results show that the proposed method can effectively improve the current-tracking performance.
