本論文最主要的目的在於探討如何針對橫向磁場式開關磁阻型線性電動機建立其週邊及驅動電路，並推導其數學模型，以分別實現懸浮力與速度之控制，並引進任務週期分配法則，來實現同步控制之要求。論文中提出以數位信號處理器(DSP)為設計線性電動機控制器之基礎，結合模糊控制理論為控制之方法，並對過去有關電動機的研究加以討論，以改進其硬體架構及理論分析等部分。此外應用一般傳統旋轉電機之qd0正交座標軸轉換分析法，來解決因特殊電機設計而造成控制不易的問題。如此方能藉由控制正交軸上的磁交鏈來達成懸浮力控制，以減少重力之影響，進而降低因摩擦造成的能量損耗，同時分配懸浮力控制與速度控制所需的比重，來達成當控制懸浮力時，電動機仍可繼續以穩定速度的運作。

The objective of this thesis is to present the algorithm of achieving speed and lift force controls of transverse flux linear switched-reluctance machine (LSRM) simultaneously. A high-speed digital signal processor based (DSP-based) switching controller will be implemented, and the desired speed control objective is realized by using a fuzzy control scheme. On the other hand, by using an indirect field-oriented control scheme, the LSRM reluctance forces, which are magnetically decoupled and position dependent, can be projected onto sets of stationary axes that are aligned with the motor fixed secondary poles. Hence by controlling flux on the specific stationary axis, the machine lift force can be properly controlled. Finally, adequate duty cycle distribution will be discussed and examined to asynchronously supply the required speed and lift force control objectives simultaneously.
