碩士 === 國立臺灣海洋大學 === 電機工程學系 === 106 === This thesis proposes model and model-free modulated predictive current controllers, for interior permanent magnet synchronous motor (IPMSM). Both predictive current controllers can apply two modulated voltage vectors in each sampling period, where the modulated mechanism is based on optimization calculations. Through the arrangements and combinations of the two voltage vectors, up to twenty-five switching modes can be obtained. Next, an optimal switching mode is selected from among them, which has the minimum cost value, and thus the inverter can be controlled directly in the next sampling period. For fair performance comparisons, both the proposed controllers and existing two ones are implemented by a Texas Instruments (TI) microcontroller TMS320F28377S. Finally, the feasibility and effectiveness of the proposed controllers can be verified in the experimental and quantitative results.
