In this paper, structural controllability of a leader-follower multi-agent system with multiple leaders is studied from a graph-theoretic point of view. The problem of preservation of structural controllability under simultaneous failures in both the communication links and the agents is investigated. The effects of the loss of agents and communication links on the controllability of an informa...

Influence diagram is a graphical representa­ tion of belief networks with uncertainty. This article studies the structural properties of a probabilistic model in an influence diagram. In particular, structural controllability the­ orems and structural observability theorems are developed and algorithms are formulated. Controllability and observability are funda­ mental concepts in dynamic syste...

We examine the role of structural autapses, when a neuron synapses onto itself, in driving network-wide bursting behavior. Using a simple spiking model of neuronal activity, we study how autaptic connections affect activity patterns, and evaluate if controllability significantly affects changes in bursting from autaptic connections. Adding more autaptic connections to excitatory neurons increas...

We investigate the internal controllability of the wave equation with structural damping on the one dimensional torus. We assume that the control is acting on a moving point or on a moving small interval with a constant velocity. We prove that the null controllability holds in some suitable Sobolev space and after a fixed positive time independent of the initial conditions.

This paper studies the controllability of networked relative coupling systems (NRCSs), in which subsystems are fixed high-order linear dynamics and coupled through variables depending on their neighbors, from a structural perspective. The purpose is to explore conditions for subsystem network topologies under almost all weights interaction links, corresponding numerical NRCSs controllable, call...
