摘要

本篇文章探討一個架構在史密斯預估器上的延遲系統，主要目的是要對未知的延遲時間做預測。利用基本的模糊邏輯控制器來做為估測器。此方法使得系統控制器可以視為只控制一個非延遲受控體系統，大幅地簡化延遲系統中繁雜的控制器設計。模擬結果也成功地顯示了延遲時間的估測，而系統也因此而獲得穩定。

並列摘要

In this paper, a fuzzy estimator based on the Smith predictor for a time-delay system is proposed. The purpose of this work is to predict the unknown plant time-delay by using a fuzzy logic controller. Only a classical controller is considered to deal with a non-time-delay system. The proposed method makes easy the controller design for a time-delay system. To show the validity and effectiveness of the proposed method, simulation results show that the unknown time-delay can be predicted successfully. Further, the improving response can be also obtained.
