  • In this paper, we present an international benchmark used in the adaptive control specialist community in order to evaluated the fuzzy control performances. Before solving the corresponding problems, we introduce some improvements on a classic fuzzy controller in order to consider high order systems and time delays. At the end of this paper, the simulation results obtained with the extended Fuzzy Controller will be compared with those obtained with a Supervised Adaptive Controller.

  • 본 연구에서는 방사선치료장치의 몬테칼로 시뮬레이션에 널리 이용되는 BEAM 코드를 이용하여 Siemens사의 Primus 선형가속기 다엽콜리메이터(MLC)를 모델링한 후 그 적합성을 측정 데이터와의 비교를 통하여 검증하였다. 모델링을 위해 Primus 선형가속기의 다엽콜리메이터의 치수를 실측하였고 근사화를 통해 VARMLC 모듈을 사용하여 모델링하였다. 모델링 시에 leakage 및 tongue-and-groove 효과를 고려하였다. 시뮬레이션 결과는 필름 측정 결과와 잘 일치함을 확인하였으며, 본 연구에서의 방법이 Siemens 사의 다엽콜리메이터의 모델링에 유효함을 확인할 수 있었다.

  • This paper introduces the Performance Monitoring System(PMS) in a thermal power plant. The purpose of the PMS is to offer the operator current performance information of plant which could be an index of plant status or information to improve plant efficiency. The PMS of Bukcheju thermal power plant unit #2&3 is implemented under the SIEMENS DCS which supplies about 150 function blocks for performance calculation and all measured signals. The performance of unit, boiler, turbines, feedwater heaters, condenser, airpreheaters, feedwater pumps will be monitored and updated for every 5 minutes in PMS of Bukcheju TPP.

  • We are using the Faraday's electromagnetic law so as to improve our life in various industry fields. However, the side effect of the Faraday's law can be occurredin the sensors of the vehicle due to the high current flow such as Ignition. This effect is mainly caused by the shape of the wiring harness between sensor and high current load in the vehicle. To minimize the side effect by Faraday's law, three methods shall be considered in this paper (1) Pin definition of the sensor, (2) Pin definition of the high current load, (3) Wiring harness shape.

  • We describe six important defuzzification methods and their respective merits and shortcomings, dependent on the rules, domains, etc. Furthermore, we present an alternative approach, the so called ξ-Quality defuzzification method, for the case that the output fuzzy sets have different shape or are asymmetric.
