In this study a MRAC(model reference adaptive control) for fluid power elevator model system was designed. The MRAC was compared with PI control in case of applying to the elevator model system with constant external load and changing external load. In this case external load was produced by a single fluid power cylinder combined with pressure control valve. In conclusion the MRAC control performance was better than PI control performance because overshoot and steady state error of the elevator model system controlled by the MRAC were not appeared for constant and changing external load.

In this paper, a new design method for Assembly Line Control System(ALCS) is presented. This system consists of five independent modules having their own specific functions such as production management, facility management material management, quality management, and remote control. To implement the ALCS, we propose design of the common data management module(CDMM). This module has the roles of integrating the above five modules and of communicating the common data between them. Using this method, we realize an information management method in the view of CIM. In addition, we standardize the inter-communication of common data between machines having different interface protocols.

Injection molding machine is the assembly of many kinds of mechanical and fluid power part and electro-electronic control system. From in these, fluid power is a part where becomes the first core of this machine. Fluid power systems of injection molding machine are modelled and analyzed using a commercial program AMESim. The analysis model which is detailed about the parts applied a publishing catalog data. Sub system models which is divided according to functional operation are made and its analysis results shows how design parameters work on operational characteristics like displacement, pressure, flow rates at each node and so on. Total fluid power circuit model is also made and analyzed. The results made by analysis will be used design of fluid power circuit of injection molding machine.
