摘要

由於業界普遍要求高轉速及高精度，磁浮軸承已越來越受到重視。相較於傳統八極磁浮軸承，三極磁浮軸承於降低成本上有更大優勢。因為製程的進步及控制理論成熟，飛輪儲能系統逐漸抬頭，結合磁浮軸承將是一塊具有前瞻性的發展領域。本論文的磁浮系統為了搭配儲能系統，希望能以最少能量來使系統抵達穩定狀態，因此選用了適應性自我平衡控制，在系統穩態之時，毋須輸入電流即可穩定旋轉於慣性主軸；並且為了使系統具有強健性，搭配了積分滑動模式控制。最後我們透過模擬與實驗來驗證控制之可行性。

Due to the industry depend on high speed and high accuracy, magnetic bearings have attracted more and more attention. Comparing between 8-pole and 3-pole magnetic bearings, the latter is much better on reducing the manufacturing cost. Because of the development of manufacturing and control theorems, flywheel energy storage system (FESS) emerges gradually, and FESS combined with magnetic bearings would become a forward-looking area of development. In order to match the FESS, the magnetic bearing system proposed in this paper intends to control the system with the least energy, therefore I chose Adaptive Autocentering Control (AAC), as system reaches steady state, no current input system, and it contains rotate around the principal axis of inertia. In addition, the control law includes Integral Sliding Mode Control (ISMC) for robustness. Eventually, both numerical and experimental results are used to verify the effectiveness of the controllers.
