本篇論文中，我們針對脈波寬度調變的研究方向設計了一個可變結構系統的脈寬調變控制器，這個設計改善了可變結構控制中會出現的擾動問題，進而再探討這可變結構控制的脈寬調變系統之穩定度問題，其中我們利用Lyapunov 直接方法與線性矩陣不等式的方法分析系統的穩定度，並且間接地找出系統要穩定下的可變結構系統之脈寬調變控制器。

In this thesis, we aims at the studies of PWM systems and design a VSS PWM controller. The chattering problems of VSS control system is improved in this thesis. Furthermore, we discuss stability problems of VSS PWM control systems. By using Lyapunov direct method and linear matrix inequality method, find the VSS PWM controller under the conditions which systems are ensured being stable.
