The simulators for pump operation developed by domestic or overseas research have been developed for dynamic analysis or operator training purposes. However, previous developed simulators focused on the operators so they are unsuitable for logic designers or commissioning engineers who need to change the operation conditions or logics arbitrarily. In addition, the simulator for two or more condensate pumps' operation, which can be used easily by plant designers or operators, has not been developed. Accordingly, this paper suggests a simulation method that can be used easily for plant designers or operators using MATLAB Simulink. This suggestion helps users who can use MATLAB to implement ANSI/ISA S5.2, which is applied mainly for DCS (Distributed Control System). In addition, to implement the logics specified in the CODE, Sub-Systems were created for the block and evaluated to determine if they can be used in the simulator. In the working level stage using the suggested method, all error possibilities that might occur during the three pumps' rotation operation could be verified with the suggested simulator during the design stage or before operation.

In this paper, a computer simulation tool for evaluting integrated engine/transmission control system using MATLAB/SIMULINK is investigated. Since a modular programming technique based upon the object-oriented programming is used in the paper, the simulation tool developed reduces the burden of model complexity by dividing engine/transmission systems into hierarchical subsystem. Furthermore, it also provides user -friendly, reusable, and upgradable characteristics of the system. The simulation tool could be useful to the automotive engineers who frequently change models and develop new systems in the automotive powertrain and control area.

칼만이론 및 Unscented 변환 기반의 Unscented 칼만필터를 이용하여 동적위치제어시스템을 설계하였다. Unscented 칼만필터는 기존의 칼만필터처럼 비선형운동방정식을 선형화 할 필요없이 비선형운동방정식 그대로 사용할수 있다. Unscented 칼만필터를 이용하여 설계한 동적위치제어시스템을 MATLAB SIMULINK프로그램을 이용하여 해양선박에 대해 컴퓨터시뮬레이션을 진행하였다.

This paper presents the dynamic characteristic analysis of Permanent Magnet Linear Synchronous Motor(PMLSM) according to variable load. In order to analyze dynamic characteristics, finite element method(FEM) was used for calculation of the parameter and the Matlab simulink was used for dynamic characteristic simulation. The measuring system of the dynamic characteristics was manufactured and the experiment results were compared with the simulation results.

The effect of bypass diodes on the output energy of solar cells was investigated under the condition of partial shading. The maximum power point was estimated using the perturbation & observation algorithm, taking into account the correlation effect between the arrangement and number of bypass diodes. The performance of the bypass diode was tested under the consideration of the partial shading effect and simulated using a Matlab/Simulink.
