Real-Time Distributed Control and Simulation of a Physical Emulator of a Flexible Manufacturing System

This research addresses the preparation of a testbed to be used in developing the intelligent controller for complex discrete-event systems and the development of new software tools that will assist in the specification of included controllers. In particular, a physical emulator of a flexible manufacturing system (FMS) has been constructed. This emulator is being controlled by a simulation model that employs our new coordination architecture (which distributes both planning and control) called Recursive Object-Oriented Control Hierarchy (ROOCH). The future development of the intelligent controller will also rely heavily upon the same simulation model. The simulation model was written using our new simulation approach for modeling FMSs and other discrete-event systems employing the ROOCH architecture, called Hierarchical Object Oriented Programmable Logic Simulator (HOOPLS). This simulation approach models the interactions among the distributed controllers. The HOOPLS simulation model presented here can be used to assess the future performance of the system. In order to demonstrate this ability the method for performing real-time simulations is discussed where the state information is collected from the physical emulator and a simulation is initiated from this recorded state.
