Mobile wire technology is a publicly available general purpose for Radio Frequency(RF) communication for short-range and point-to-multi point voice and data transfer. In this paper, we proposed a new technology of the synchronized frame structure which is based on the CDMA technique, and it's implemented into the VLSI design by FPGA. The developmental technique consists of an assigned coded type mobile communication equipments and available local mobile or wireless communication scheme quasi BT(Blue Tooth)'s functions as multiplexer or do-multiplexer for each other applications. We implement this architecture with special proposed frame structure in the local area network. Also, we expect the above proposed structure extend into the DS3 network architecture and applicable to the TE(Terminal Equipment) in the local communication area and the other one etc.

본 논문에서는 간편 간접추론방법을 이용한 퍼지 디지털 PID 제어기의 설계 방법을 제안하였다. 제안된 퍼지 제어기는 선형 디지털 PID 제어기에서 유도하였으며, 간편 간접추론을 이용한 퍼지화부, 제어규칙 베이스 및 퍼지화부의 설계방법을 설명하였다. 제안된 퍼지 제어기는 종래의 디지털 PID 제어기를 기초로 설계하였으므로 구조를 이해하기 쉽고, 퍼지입력에 의한 비선형 특성을 가지므로 선형 및 비선형 플랜트에 적응 능력을 가진다. 또한 각 입력변수 별로 간편 간접추론방법을 사용하여 추론하므로 고속 추론이 가능하고, 퍼지규칙의 수가 증가하여도 쉽게 적용 가능하다. 제안된 제어기의 성능을 D. Misir 등이 사용한 선형 및 비선형 플랜트에 모의 실험하여 효용성을 입증하였다.

This research is concerned with the active vibration controller design for smart structures by a modified LQG controller. The smart structure is defined as the structure equipped with smart actuators and sensors. Various analog and digital control, techniques aimed for the piezoceramic sensors and actuators have been proposed for the active vibration control of smart structures. In this paper, the modified LQG controller is developed for the active vibration suppression of smart structures to implement the predefined decay rate on modal displacements. The proposed modified LQG controller proved its effectiveness by experiments.

This paper presents a fuzzy modified PID controller that uses linear fuzzy inference method. In this structure, the proportional and derivative gains vary with the output of the system under control. 2-input PD type fuzzy controller is designed to obtain the varying gains. The proposed fuzzy PID structure maintains the same performance as the general-purpose linear PID controller, and enhances the tracking performance over a wide range of input. Numerical simulations and experimental results show the effectiveness of the fuzzy PID controller in comparison with the conventional PID controller.
