Synchronized Cooperative Simulation:

چکیده
Most simulation tools excel at only one technical domain. For efficient simulation of multi-domain systems, cooperative simulation (co-simulation) can be used. In co-simulation, a simulation model is divided into smaller submodels to allow each of the submodels to be simulated with a purpose-made simulator. The connectivity between the multiple simulators is a key factor in the performance of a co-simulation. In this work, the OPC UA standard was chosen as the communication interface between the different simulators. OPC UA is considered an effective communication interface and, moreover, the versatility of OPC UA allows the same interface to be utilized by the user to control and configure the co-simulation. In this thesis, the core functionalities of an effective and scalable synchronized co-simulation environment were designed and implemented. As an important part of the work, a novel solution for OPC UA based synchronization in continuous dynamic co-simulation is proposed. The evaluation conducted on the implementation confirms that both the synchronization solution and the OPC UA interface are suitable for being used in co-simulation of real-world systems.

A Distributed Cooperative Control Framework for Synchronized Reconnection of a Multi-Bus Microgrid
One critical value microgrids bring to power systems is resilience, the capability of being able to island from the main grid under certain conditions and connect back when necessary. Once islanded, a microgrid must be synchronized to the main grid before reconnection to prevent severe consequences. In general, synchronization of a single machine with the grid can be easily achieved using a syn...
متن کاملA Paradigm for Dynamic Coordination of Multiple Robots
In this paper, we present a paradigm for coordinating multiple robots in the execution of cooperative tasks. The basic idea in the paper is to assign to each robot in the team, a role that determines its actions during the cooperation. The robots dynamically assume and exchange roles in a synchronized manner in order to perform the task successfully, adapting to unexpected events in the environ...

متن کاملBio-Inspired Adaptive Cooperative Control of Heterogeneous Robotic Networks
We introduce a new adaptive cooperative control strategy for robotic networks comprised of heterogeneous members. The proposed feedback synchronization exploits an active parameter adaptation strategy as opposed to adaptive parameter estimation of adaptive control theory. Multiple heterogeneous robots or vehicles can coordinate their motions by parameter adaptation analogous to bio-genetic muta...
