本文探討一部3相1仟瓦，36槽，12極的外轉子表貼式永磁同步電動機驅動系統。此部外轉子式電動機與內轉子式不同，轉子位於電動機外側，因此在運轉時的轉動慣量較大。此外，極數為12極亦較常見的內轉子式4極更多，為了擴展高速運轉範圍，本文中探討弱磁控制來讓電動機運轉在高於額定轉速之上，並且採用最大轉矩/伏特，進一步擴展高速範圍。
本文亦探討預測型速度控制器與預測型電流控制器取代傳統比例-積分控制器，改善閉迴路驅動系統的動態速度響應，及減少電動機的電流諧波，以提升電動機的整體性能。包括:良好的加載回復能力、快速的動態響應等。
本文使用德州儀器公司所生產的數位訊號處理器，編號為TMS320F28035 ，進行驅動系統的核心控制，實驗結果說明本文所提方法的可行性與正確性。

This thesis investigates a 3-phase, 1kW, 36-slot, 12-pole outer rotor surface-mounted permanent-magnet synchronous motor (SPMSM) drive system. Compared to a regular internal rotor SPMSM, this outer rotor SPMSM has a higher inertia and also has 12 poles, which is higher than regular internal rotor which has 4 poles.
In order to extend the high speed operating range, the flux-weakening control is studied to operate the outer rotor SPMSM beyond its rated speed. In addition, the maximum torque/volt is also investigated.
This thesis also proposes a predictive speed controller and a predictive current controller to replace the PI controllers, and then improve its closed-loop dynamic response, and also reduces harmonic currents. These improvements include achieving better recovery ability and obtaining better transient dynamics.
A digital signal processor, typed TMS-320F-28035, manufactured by Texas Instruments, is used as a control center for the outer rotor SPMSM drive system. Experimental results validate the feasibility and correctness of the proposed methods.
