Leader-following Consensus of Multi-agent Systems over Finite Fields
The leader-following consensus problem of multi-agent systems over finite
fields is considered in this paper. Dynamics of each agent is
governed by a linear equation over , where a distributed control
protocol is utilized by the followers.Sufficient and/or necessary conditions on
system matrices and graph weights in are provided for the
followers to track the leader
Synchronization of Diverse Agents via Phase Analysis
In this paper, the synchronization of heterogeneous agents interacting over a
dynamical network is studied. The edge dynamics can model the inter-agent
communications which are often heterogeneous by nature. They can also model the
controllers of the agents which may be different for each agent or uniform for
all the agents. Novel synchronization conditions are obtained for both cases
from a phase perspective by exploiting a recently developed small phase
theorem. The conditions scale well with the network and reveal the trade-off
between the phases of node dynamics and edge dynamics. We also study the
synchronizability problem which aims to characterize the allowable diversity of
the agents for which controllers can be designed so as to achieve
synchronization. The allowable diversity is captured in terms of phase
conditions engaging the residue matrices of the agents at their persistent
modes. Controller design algorithms are provided for the cases of
agent-dependent and uniform controllers, respectively
The role of local bounds on neighborhoods in the network for scale-free state synchronization of multi-agent systems
This paper provides necessary and sufficient conditions for the existence of
solutions to the state synchronization problem of homogeneous multi-agent
systems (MAS) via scale-free linear dynamic non-collaborative protocol for both
continuous- and discrete-time. These conditions guarantee for which class of
MAS, one can achieve scale-free state synchronization. We investigate protocol
design with and without utilizing local bounds on neighborhood. The results
show that the availability of local bounds on neighborhoods plays a key role.Comment: This paper was submitted to IJRNC on Aug. 3, 2023 and resubmitted on

Scale-free Non-collaborative Linear Protocol Design for A Class of Homogeneous Multi-agent Systems
In this paper, we have focused on identifying a class of continuous- and
discrete-time MAS for which a scale-free non-collaborative (i.e., scale-free
fully distributed) linear protocol design is developed. We have identified
conditions on agent models that enable us to design scalable linear protocols.
Moreover, we show that these conditions are necessary if the agents are single
input and single output. We also provide a complete design of scalable
protocols for this class.Comment: This paper was submitted to IEEE Transactions on Automatic Control at
