Conventional predictive torque control (Conv-PTC) has the advantages of fast dynamic response and simple algorithm structure. However, Conv-PTC has drawbacks in terms of torque and current quality, since the voltages are applied within limited voltage vectors, which have real switching states. The proposed predictive torque control with space vector modulation (PTC-SVM) method provides various virtual voltage vectors generated near the estimated voltage angle. A number of virtual voltage vectors give an effect for selecting optimal values to follow the reference torque, flux, or currents. Furthermore, voltage vectors generated based on the voltage angle not only reduce steady-state errors but also allow for fewer calculation numbers to be maintained. The effectiveness of the proposed PTC using the SVM method for driving OEW-IPMSM is proved by simulation and experimental results compared to Conv-PTC. 제 1 장 서론 1_x000D_ <br>제 2 장 이중 인버터로 구동하는 OEW-IPMSM 4_x000D_ <br>2.1 이중 인버터의 스위칭 함수에 따른 전압 모델링 방정식 4_x000D_ <br>2.2 OEW-IPMSM 의 전압 모델링 방정식 6_x000D_ <br>제 3 장 OEW-IPMSM 운전을 위한 일반적인 토크 예측 제어 기법 8_x000D_ <br>3.1 OEW-IPMSM 의 이산 시간 전류 모델 8_x000D_ <br>3.2 후보 전압 벡터 및 비용함수 10_x000D_ <br>제 4 장 제안하는 공간 벡터 변조 방식의 토크 예측 제어 기법 12_x000D_ <br>4.1 OEW-IPMSM 의 전압 각 추정 12_x000D_ <br>4.2 가상 전압 벡터 생성 방법 13_x000D_ <br>4.3 공간 벡터 변조 및 데드타임 보상 15_x000D_ <br>제 5 장 시뮬레이션 결과 17_x000D_ <br>5.1 시뮬레이션 회로도 및 파라미터 17_x000D_ <br>5.2 시뮬레이션 결과 19_x000D_ <br>제 6 장 실험 결과 22_x000D_ <br>6.1 실험 세트 및 환경 22_x000D_ <br>6.2 제안하는 PTC-SVM 기법 실험 결과 23_x000D_ <br>제 7 장 결론 29_x000D_ <br>참고문헌 30 kor The Graduate School, Ajou University 아주대학교 논문은 저작권에 의해 보호받습니다. 공간 벡터 변조 방식을 이용한 개방 권선형 매입형 영구자석 동기 전동기의 전압 각 기반 토크 예측 제어 Predictive Torque Control of Open-End Winding Interior Permanent Magnet Synchronous Motor Based on Voltage Angle Using Space Vector Modulation Thesis 아주대학교 대학원 Tae-Yong Yoon 일반대학원 전자공학과 2024-02 Master https://dcoll.ajou.ac.kr/dcollection/common/orgView/000000033518 open-end winding interior permanent magnet synchronous motor (OEW-IPMSM) perdictive torque control (PTC) predictive torque control with space vector modulation (PTC-SVM) space vector modulation (SVM) torque ripple reduction This thesis proposes predictive torque control (PTC) based on voltage angle using the space vector modulation (SVM) method for driving an open-end winding interior permanent magnet synchronous motor (OEW-IPMSM) fed by a dual inverter.
