Distributed statistical estimation of the number of nodes in sensor networks
The distributed estimation of the number of active sensors in a network can be important for estimation and organization purposes. We propose a design methodology based on the foll...

Relaxing LMI domination matricially
Given linear matrix inequalities (LMIs) L1 and L2 in the same number of variables it is natural to ask: (Q1) does one dominate the other, that is, does L1(X) 0 imply L2(X) 0? (Q2) ...

Stokes-Dirac structures through reduction of infinite-dimensional Dirac structures
Abstract-- We consider the concept of Stokes-Dirac structures in boundary control theory proposed by van der Schaft and Maschke. We introduce Poisson reduction in this context and ...

Control of large 1D networks of double integrator agents: Role of heterogeneity and asymmetry on stability margin
We consider the distributed control of a network of heterogeneous agents with double integrator dynamics to maintain a rigid formation in 1D. The control signal at a vehicle is all...

Left invertibility of output-quantized systems: An application to cryptography
ABSTRACT. In this paper a secure communication method is proposed, based on left invertibility of output-quantized dynamical systems. The sender uses an output-quantized linear sys...

An adjoint method for second-order switching time optimization
Abstract-- Switched systems evolve over a sequence of continuous modes of operation, transitioning between modes in a discrete manner. Assuming a mode sequence is known, the evolut...

Multi-robot monitoring in dynamic environments with guaranteed currency of observations
Abstract-- In this paper we consider the problem of monitoring a known set of stationary features (or locations of interest) in an environment. To observe a feature, a robot must v...
