We study decentralized controller design for stabilization and pole-placement, in a network of autonomous agents with double-integrator internal dynamics and arbitrary observation topology. We show that a simple multi-lead-compensator architecture, in particular one in which each agent uses a derivative-approximation compensator with three memory elements, can achieve both stabilization and effective...
In this article, we introduce a promising methodology for designing stabilizing and high-performance yet practical topology-exploiting dynamic controllers for LTI decentralized systems, that is fundamentally based on 1) envisioning a control architecture with direct local feedback of multiple derivatives of the observation and 2) using multi-lead-compensator and multiple-delay control schemes to implement...

We motivate the problem of designing a subset of the edge weights in a graph, to shape the spectrum of an associated linear time-invariant dynamics. We address a canonical design problem of this form by applying time-scale assignment methods, and give graph-theoretic characterizations of the designed dynamics.
We develop a control methodology for linear time-invariant plants that uses multiple delayed observations in feedback. Using the special coordinate basis (SCB), we show that multiple-delay controllers can always be designed to stabilize minimum-phase plants, and identify a class of non-minimum-phase plants that can be stabilized using these controllers.
Motivated by network controller design applications, we develop several majorization results for the dominant eigenvector of an irreducible nonnegative matrix.
We motivate and address the optimal scaling problem, i.e. the problem of designing a diagonal matrix K so as to 1) place the eigenvalues of KG in the open right half plane and 2) optimize a scalar performance measure c(KG), for a given topology matrix G
