Consensus for switched networks with unknown but bounded disturbances
We consider stationary consensus protocols for networks of dynamic agents
with switching topologies. The measure of the neighbors' state is affected by
Unknown But Bounded disturbances. Here the main contribution is the formulation
and solution of what we call the -consensus problem, where the states
are required to converge in a tube of ray asymptotically or in
finite time.Comment: 18 pages, 3 figures. The manuscript has been submitted for the

Dynamic Models of Appraisal Networks Explaining Collective Learning
This paper proposes models of learning process in teams of individuals who
collectively execute a sequence of tasks and whose actions are determined by
individual skill levels and networks of interpersonal appraisals and influence.
The closely-related proposed models have increasing complexity, starting with a
centralized manager-based assignment and learning model, and finishing with a
social model of interpersonal appraisal, assignments, learning, and influences.
We show how rational optimal behavior arises along the task sequence for each
model, and discuss conditions of suboptimality. Our models are grounded in
replicator dynamics from evolutionary games, influence networks from
mathematical sociology, and transactive memory systems from organization
science.Comment: A preliminary version has been accepted by the 53rd IEEE Conference
