“…서론 자기부상시스템(magnetic levitation system)은 자기력을 이용 하여 물체를 부상시키는 장치로서 소음 및 기계적 마찰이 없 다는 장점 때문에 고속 회전체의 자기 베어링, 자기부상 열 차 등 다양한 산업분야에 응용되고 있다 [1][2][3][4]. 또한 자기부상 시스템은 피드백 제어의 개념을 익히려는 학습자를 위한 교 육용 시스템으로도 자주 활용된다 [5,6]. 자기부상시스템은 비 선형 시스템이고 불안정한 시스템이기 때문에 제어이론의 학습목적 뿐만 아니라 새로운 제어이론을 적용하여 성능 및 타당성을 평가하기에도 알맞은 시험표준(benchmark) 시스템 이다.…”

This paper proposes an equipment and an algorithm for modeling the magnetic force of electromagnets in magnetic levitation systems. We assume that the magnetic force model is represented in terms of a 2D lookup table. The 2D lookup table is constructed by applying noncausal filtering and interpolation to data measured by the proposed modeling equipment. The proposed modeling equipment is designed such that it can measure the magnetic force exerted on the levitation object while it changes the voltage applied to the electromagnet and position of the levitation object. The algorithm of making a 2D lookup table has two stages. The data measured by the proposed modeling equipment is smoothed by a noncausal filter and then the 2D lookup table is obtained by interpolating filtered data. The proposed modeling method has advantages of time-saving, model consistency, and chance of automation for mass production. We show the validity of proposed method through control experiments.

Abed, Nagy Youssef, "Physical dynamic simulation of shipboard power system components in a distributed computational environment" (2007 In order to perform system studies in such an environment physical phase variable models of different components of the shipboard power system were developed using operational parameters obtained from finite element (FE) analysis.These models were developed for two types of studies low and high frequency studies. Low frequency studies are used to examine the shipboard power systems v behavior under load switching, and faults. High-frequency studies were used to predict abnormal conditions due to overvoltage, and components harmonic behavior. Different experiments were conducted to validate the developed models. The Simulation and experiment results show excellent agreement.The shipboard power systems components behavior under internal faults was investigated using FE analysis. This developed technique is very curial in the Shipboard power systems faults detection due to the lack of comprehensive fault test databases.A wavelet based methodology for feature extraction of the shipboard power systems current signals was developed for harmonic and fault diagnosis studies.This modeling methodology can be utilized to evaluate and predicate the NPS components future behavior in the design stage which will reduce the development cycles, cut overall cost, prevent failures, and test each subsystem exhaustively before integrating it into the system.
