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.
