數位訊號處理器(DSP)為主體之永磁式無刷馬達控制在本論文中作深入的理論分析與控制器實作，使用全新的改良式輸出回授可變結構控制理論，經由實驗結果證實其應用在永磁無刷伺服馬達上是可行而且效果極佳。
在論文中的理論分析藉由線性矩陣不等式方法應用在非匹配不確定輸出回授可變結構系統，經由此線性矩陣不等式之理論能有效減少非匹配不確定成份在輸出回授順滑模態下的不良影響，保證系統穩定而且性能良好。
另外，由於大型系統的控制問題日益重要，本文再進一步探討非匹配不確定大型系統的穩定性和顫動問題之解決方法，在大型系統的各子系統中，我們藉由使用一個虛擬的控制，去證明系統的穩定度。為了改善顫動問題，提出一個連續式滑動模式控制器去處理，此一新的分散式可變結構控制器證明是穩定且具有良好的動態特性。

A Digital Signal Processor (DSP) based brushless Permanent Magnet (PM) motor control doing the theory analysis and experimental in this dissertation. Using the new modified variable structure control theory, the experiment result shown that the new output controller is feasible on the control of brushless PM motor.
The Linear Matrix Inequality (LMI) method which is applied for dynamic output feedback for mismatched uncertain Variable Structure System (VSS). Using this new LMI theory based output feedback Variable Structure Control (VSC), the mismatched variable structure systems is asymptotically stable with good performance.
In addition, because of the large-scale systems control problem are asymptotically important. We discuss the solved method with the stabilization and chatting problem of large-scale systems with mismatched uncertain. In the subsystem, a fictitious control is presented to prove the stability. In order to improve the chatting problem, we use a continuous sliding mode controller to deal with the chatting problem. We propose new decentralized variable structure controller which guarantees the stability without chattering problem.
