This paper proposes a distributed simulator for general control system in CEMTool. Systems can be described by SIMTool likes the simulink in Matlab. For distributed simulation, we can seperate any system into several parallel subsystems in SIMTool. The number of parallel subsystem can be determined by the system's property. After seperation, parallel simulator will do initialization, one-step-ahead simulation, block-distribution and ordering and so on. Finally, simulator will create independent C codes and executive files for each subsystem. The whole system is fulfilled by several PCs, and each PC executes one subsystem. There are communications among these subsystem using reflective memory or ethernet. We have made several experiments, and the 5-stand cold rolling mill control system is our main target. The result of parallel simulation has shown effective speedup in comparison with one pc simulation.

In this paper, we try to develop the controller which uses the block diagrams of SIMTool and internal functions CEMTool for planning the global driving controller for high efficiency AGV. We acquire the control efficiency by controlling the motor used each part of AGV driving controller. The block diagram structures provided with SIMTool is easily designed by the controller, and the monitoring and analysis of the results is researched by simulation. We expect to control AGV. robot and various plant using Ziegler-Nichols auto-tuning method and external I/O board

A controller was designed generally using C or assembly languages on high-speed design controller. But, in this paper, DC servo controller is designed using the cord of the block-diagram of SIMTool. By the method, we can design, realized and analyzed a control system quickly in real-time. And we expect that the various plants of a robot vehicles are controled through the outside I/O board changing the structure of the block-diagram of SIMTool into AUTOTool. In addition, our developed system helps the most suitable automatic controller design and tester with hight-speed.

본 논문에서는 CEMTool환경에서 수행된는 일반적 형태 분산 시뮬레이터의 구조를 제안한다. 먼저, 분산시뮬레이션을 할 수 있도록 SIMTool에서 전체 시스템을 패럴랠블록의 형식으로 여러개의 서브시스템으로 분할한다. 그런후에 CEMTool환경에서 분할된 시스템에 대하여 초기화, one step ahead 시뮬레이션, distribute와 ordering의 과정을 진행한 후 각각의 서브시스템에 대하여 독립적인 C code과 실행파일을 생성한다. 여러 대의 PC에서는 분할된 각각의 서브시스템을 독자적으로 실행시키는 동시에 서로간에 reflective memory를 통해 데이터를 주고반는다. 본 논문의 실험대상인 냉간압연 시스템은 각각의 서브시스템 내부의 계산량이 통신량보다 훨씬 많기 때문에 분산처리를 하기에 아주 적합하며, 본 논문에서는 냉간압연 시스템에 대한 분산시뮬레이션의 결과를 분석하고 제시된 방법으로 확실한 속도향상의 결과를 보여준다는 것을 설명하고자 한다.

This paper shows the result of development about the revolution system of azimuth thruster which of power is less than 250kW for small ship. Advanced Azimuth revolution system can revolve propeller and rudder from 360 degree so that this system for vessel maneuvering can be excellent of propulsion effectively. Fluid power control system for azimuth thruster is designed with PID control system by using CEMTool/SIMTool program. And the actuator used for servo valve can control rudder angle, pressure and direction. The first, We had a test for the angle control of revolution system. The result of angle control confirmed that it has the good efficiency from experiment result of time input degree $30^{\circ}$, $90^{\circ}$ and $180^{\circ}$. The second, We had to a test for the pressure characteristic of hydraulic motor. As a result, We confirmed the maximum pressure 3.5MPa and steady state 0.7MPa nom experiment result of time input degree $30^{\circ}$. In this paper, it is identified the pressure characteristic of hydraulic motor and angle control for azimuth thruster by AMESim, and it has been confirmed the usefulness of AMEsim modeling was verified by comparison between AMESim simulation results and experiments results.
