in this talk, a recently on the teleoperation of sward robotics will be introduced. during swarm teleoperation, the human operator may threaten the distance-dependent inter-robot communications and, with them, the connectivity of the slave swarm. to prevent the harmful component of the human command from disconnecting the swarm network, we develop a constructive strategy to dynamically modulate the interconnections of, and the locally injected damping at, all slave robots. by lyapunov-based set invariance analysis, the explicit law for updating that control gains has been rigorously proven to synchronize the slave swarm while preserving all interaction links in the tree network. by properly limiting the impact of the user command rather than rejecting it entirely, the proposed control law enables the human operator to guide the motion of the slave swarm to the extent to which it does not endanger the connectivity of the swarm network.

in this talk, we introduce distributed continuous-time algorithms to solve the optimal resourceallocation problem with time-varying quadratic cost functions for multi-agent systems. the objective is to allocate a quantity of resources while optimizing the sum of all the local time-varying cost functions. here the optimal solutions are trajectories rather than some fixed points. we consider a large number of agents that are connected through a network, and our algorithms can be implemented using only local information. by making use of the prediction-correction method and the nonsmooth consensus idea, we first design distributed algorithms to deal with the case when the time-varying cost functions have identical hessians. we further propose estimator-based algorithms relying on distributed average tracking estimators to address the case of nonidentical hessians. in each case, it is proved that the solutions of the proposed dynamical systems with certain initial conditions asymptotically converge to the optimal trajectories. the effectiveness of the proposed distributed continuous-time optimal resource allocation algorithms are illustrated through simulations.
