H2 suboptimal containment control of homogeneous and heterogeneous multi-agent systems
This paper deals with the H2 suboptimal state containment control problem for
homogeneous linear multi-agent systems and the H2 suboptimal output containment
control problem for heterogeneous linear multi-agent systems. For both
problems, given multiple autonomous leaders and a number of followers, we
introduce suitable performance outputs and an associated H2 cost functional,
respectively. The aim is to design a distributed protocol by dynamic output
feedback that achieves state/output containment control while the associated H2
cost is smaller than an a priori given upper bound. To this end, we first show
that the H2 suboptimal state/output containment control problem can be
equivalently transformed into H2 suboptimal control problems for a set of
independent systems. Based on this, design methods are then provided to compute
such distributed dynamic output feedback protocols. Simulation examples are
provided to illustrate the performance of our proposed protocols.Comment: 15 papges, 7 figure
Partial containment control over signed graphs
In this paper, we deal with the containment control problem in presence of
antagonistic interactions. In particular, we focus on the cases in which it is
not possible to contain the entire network due to a constrained number of
control signals. In this scenario, we study the problem of selecting the nodes
where control signals have to be injected to maximize the number of contained
nodes. Leveraging graph condensations, we find a suboptimal and computationally
efficient solution to this problem, which can be implemented by solving an
integer linear problem. The effectiveness of the selection strategy is
illustrated through representative simulations.Comment: 6 pages, 3 figures, accepted for presentation at the 2019 European
