摘要


本論文旨在利用高頻注入法實現永磁同步馬達之無位置感測控制,使馬達在低轉速下亦能獲得良好的控制性能。系統架構主要包含三相三線式全橋換流器、輔助電源、永磁同步馬達與微控制器周邊電路等。控制架構分別為高頻估測器、速度控制器與電流控制器,並使用PI控制器實現。驅動器則是利用空間向量脈波寬度調變(Space Vector Pulse Width Modulation, SVPWM)驅動永磁同步馬達,並透過微控制器RX62T完成上述之控制策略,用以簡化電路、降低電路硬體成本。

並列摘要


The main objective of this thesis is to realize the position sensorless control of the Permanent-Magnet Synchronous Motor (PMSM) by using high frequency injection method. Good driving performance at low speed can be obtained via this method. The system structure includes the three-phase three-wired full-bridge inverter, auxiliary power supplies, PMSM and the peripheral circuits of the microcontroller. The control architecture includes high frequency estimator, speed controller and current controller. All the estimator and controller are realized by PI controllers. Finally, the Space Vector Pulse Width Modulation (SVPWM) is implemented to drive the motor. All control strategies are accomplished via the microcontroller RX62T. The circuit topology is simplified and the hardware cost is reduced.
