摘要

本論文提出一個控制器設針對離散時間 模糊系統使用快速輸出取樣技術之控制器設計基於離散滑動模式控制。迫近法則是一個差分方程式具能夠明確的指出滑動面函數的動態。其中系統狀態是未知並且我們不需要建構觀察器與動態補償器估測狀態。針對迴授的部份，這個方法不需要系統狀態，例如在設計控制器上唯一使用的是輸出取樣。我們將設計快速輸出取樣離散滑動模式控制法則，使系統軌跡能符合迫近法則。它既實際又容易去執行。最後，我們提出例子來驗證本文所提出的控制器對此系統的有效性。

This thesis presents a controller design for discrete-time Takagi-Sugeno (T-S) fuzzy system using a fast output sampling (FOS) technique based on discrete sliding-mode control (SMC). The reaching law is a differential equation which specifies the dynamics of a sliding surface function . The system states are unknown and we have no need to construct the observers or dynamic compensators to estimate system states. This method dose not need the system states for feedback as it make use of only the output samples for designing the controller. We will design a FOS SMC control law to ensure the system trajectories can satisfy with the reach law. It is more practical and simple to implement. Simulation results are presented to demonstrate the feasibility of the proposed control scheme.
