In this work the rendezvous problem of multiagent systems with the event-triggered control scheme is studied. Each agent is assumed to have only a limited communication range. Connectivity-preserving rendezvous controllers with bounded inputs have been developed using multiple triggers and the constraint function approach. With some very mild assumptions, existing communication links can be preserved...
From the mutual relation between hydro energy resource system and ecosystem, analyzes the theoretical basis for space-time variation of hydro energy resource system and ecosystem, and the concrete mechanism of the two systems. The study shows that seen from the smaller range of time dimension, the emphasis is embodied in different phases of hydro energy resource exploitation to ecosystem element interference,...
