Abstract:

Synchronization is a fundamental function of swarm systems in nature and can be understood as a model of coupled oscillators. Even for manmade complex systems, such as an automated guided vehicles (AGVs) system in factories, synchronization is also important to enable temporal coordination of AGVs. In the present papter, we propose a new control law for synchronization of coupled relaxation oscillators and apply it to AGV dispatch control. Our law modulates the threshold of each oscillator, which is a model of a cellular production system. We analyze the stability of the system controlled by the proposed law. It is shown that the phase dynamics of the controlled system can be reduced to those of the Kuramoto model. In addition, on the basis of a stability analysis, we produce a design procedure of the controller and verify the procedure by numerical simulation.
