본 논문에서는 DC-DC 컨버터에 적합한 퍼지제어기를 제안하였고, 이는 제어 파라메터의 변화가 심한 경우 기존의 선형 제어로는 만족할 수 없는 성능을 달성하기 위해서이다. 제안된 퍼지제어기는 범용으로 어떠한 DC-DC 컨버터 토폴로지(topologies)에도 적용할 수 있다. 퍼지 제어기 실행은 지존의 오차와 오차의 변화량에 의존하는 방식보다는 주요 상태변수를 이용하는 방식을 사용하였으며, 이는 DC-DC 컨보터의 경우 매우 효과적으로 작용하여 기존의 제어기보다 빠르고 안정적인 소신호응답 및 더욱 향상된 대신호응답을 보장하였다.예로서 부스트(boost) 컨버터에의 적용시 그 시물레이션 결과는 향상된 제어 가능성을 보여주고 있다.

With distribution industrial control system, the use of low cost to achieve a highly reliable and safe system in real time distributed embedded application is proposed. This developed intelligent node is based on two microcontrollers, one for the execution of the application code, also as master controller for ensuring the real time control & the logic operation with PLD and other for communication task and the easy control execution, i.e., I/O digital input, digital output and interrupting. This paper also presents where the case NCS (Networked control system) with LonTalk protocol is applied for the filtration process control system of a small water treatment plant.

This paper describes an intelligent system to automatic evaluation of eddy current(EC) signal for Inspection of steam generator(SG) tubes in nuclear power plant. Some features of the intelligent system design in the proposed system are : (1) separation of representation scheme ,or event capturing knowledge in EC signal and for structural inspection knowledge in SG tubes inspection; (2) each representation scheme is implemented in different methods, one is syntactic pattern grammar and the other is rule based production. This intelligent system also includes an data base system and an user interface system to support integration of the hybrid knowledge processing methods. The intelligent system based on the proposed concept is useful in simplifying the knowledge elicitation process of the rule based production system, and in increasing the performance in real time signal inspection application.

This paper describes a humanoid robot's intelligent foot with two six-axis force/moment sensors. The developed humanoid robots didn't get the intelligent feet for walking on uneven surface safely. In order to walk on uneven surface safely, the robot should measure the reaction forces and moments applied on the sales of the feet, and they should be controlled with the measured the forces and moments. In this paper, an intelligent foot for a humanoid robot was developed. First, the body of foot was designed to be rotated the toe and the heel to all directions, second, the six-axis force/moment sensors were manufactured, third, the high-speed controller was manufactured using DSP(digital signal processor), fourth, the humanoid robot's intelligent foot was manufactured using the body of foot, two six-axis force/moment sensors and the high-speed controller, finally, the characteristic test of the intelligent foot was carried out. It is thought that the foot could be used for a humanoid robot.

본 논문에서는 연산 중심의 DSP 작업에 대한 성능을 유지하면서 제어 작업을 효과적으로 수행할 수 있는 프로세서 구조를 제안하고 구현하였다. 전통적으로 DSP작업은 직렬 연결된 연산기로 구현되지만, 제안한 프로세서에서는 곱셈기, 2개의 ALU, 읽기/쓰기 유닛 등 4개의 실행 유닛이 병렬로 배치되어 있고 수퍼스칼라 방식으로 제어되므로 동시에 처리된다. 제안된 프로세서를 사용하여 AC-3 오디오 복호화기를 구현하여 성능이 37.8% 향상됨을 확인하였다. 이와 같은 연구는 기존의 고성능 DSP를 사용할 수 없는 저가격의 가전기기용 부품제작에 활용이 가능하다.
