  • This paper suggests that implementation of the Simulink execution module controls Simulink simulation and shows simulation results by applying Automata theory. This module is composed of three independent systems that the main program to accept user commands, the thread to control a simulation of Simulink model and the Simulink model to execute simulation. This paper designs each module and entire system by applying Automata theory, and implements it with C# and MATLAB language. And the Simulink execution module implemented will be verified through the experiment.

  • The DEVS (Discrete Event Systems Specification) formalism supports specification of discrete event models in a hierarchical modular manner. MATLAB/Simulink is widely used for modeling, simulating and analyzing continuous and discrete time systems. This paper proposes a realization of the DEVS formalism in MATLAB/ Simulink. The proposed design enables to use a great amount of mathematical packages and functions included in MATLAB /Simulink. The design is also employed as real time simulation and hybrid system simulation which is a mixture of continuous systems and discrete event systems. The paper introduces Simulink-DEVS model, in which a simulation algorithm is embedded. The model consists of a Simulink-atomic model and a Simulink-coupled model. In addition, the time advance algorithm to simulate the model is suggested. The algorithm handles the time synchronization and the accommodation of different concepts specific to continuous and discrete event models. Two experimental results are presented for a pure discrete event model and a hybrid model.

  • In this paper, we describe the implementation of debugger that has advanced features for verifying Simulink model. The debugger provided in Simulink has some boring and repetitive work when verifying complicated Simulink models or complicated scenarios. In order to resolve the problems, this paper addresses the issues on the implementation of debugger that provides features such as a convenient feature to compare the simulation output to the expected output for specific input, to monitor system's behavior at specific time, and coverage report function in some or all input scenarios. The proposed debugger is applied to the vending machine model provided by Matlab, demonstrating its feasibility.

  • A performacne simulation model of the PT6A-62 turboprop engine using the $SIMULINK^R$ was proposed to predict transient and steady state behaviors. The $SIMULINK^R$ has several advantages such as user-friendliness due to the GUI(Graphic User Interfaces) and ease in the modification of the computer program. The $SIMULINK^R$ model consists of subsystems to represent engine gas path components such as flight initial subsystem, compressor subsystem, burner subsystem, compressor turbine subsystem, power turbine, exhaust nozzle subsystem and integrator subsystem. In addition to subsystems, there are search subsystems to find an appropriate operating point by scaling from the 2-D components look-up table, Gasprop Subsystem to calculate the gas property precisely. In case of steady state validation, performance results analyzed by the proposed $SIMULINK^R$ model were agreed well with the analysis results by the commercial GASTURB program. Moreover in validation of the transient model, it was found that performance simulation results by the proposed model were reasonable agreement with analysis results by the well-proved computer program using FORTRAN.

  • An easier implementation method of the field oriented control of induction machine using Matlab/Simulink and dSpace board is proposed in this paper. The total system for the control of induction motor is modeled with the help of Matlab/Simulink. These models consist of induction motor block, SVPWM inverter block and control algorithm block, etc. And this system is simultaneously simulated and experimented in Matlab/Simulink environment with dSpace borad (DS1102). It is possible that Matlab and dSpace board compiler can make $^'{\ast}.c'\;and\;^'{\ast}.obj'$ file of models designed in Matlab/Simulink environment automatically. Both Simulation and experimental results are given.

  • In this study, a performance simulation program for a turbojet engine using SIMULINK, which can provide the GUI(Graphic User Interface) environment, was newly proposed. Performance analysis results using the SIMULINK performance program were compared with them using the FORTRAN performance program that was previously developed. According to comparison result, it was noted that performance analysis results between two programs have little bit big difference. This difference seems to be due to different component matching algorithm at each program, it will be improved later.

  • In this research an induction motor vector control system was developed using Simulink and RTW(Real Time Workshop). On the Simulink window, control system is designed in the form of block diagrams, program codes are produced automatically with the RTW, then c compiler compiles the program codes. With this automatic real time program producing mechanism rapid prototyping is realized without the time-consuming manual program coding procedures. To show effectiveness of the proposed designing scheme a DSP-based induction motor vector control system was constructed and implemented

  • 본 논문은 Simulink 모델을 기반으로 하여 FPGA 알고리즘을 설계하는 과정을 구현하였다. Simulink 모델은 SRF-PLL 제어기법을 적용하였으며, Simulink 모델은 기본적으로 부동소수점으로 구성된다. 그러나 FPGA 구현에 필요한 VHDL 코드는 고정 소수점 변환이 필요하므로, 부동 소수점 모델을 고정 소수점으로 변환하고 두 연산 기법의 시뮬레이션 결과를 비교분석하였다.
