This paper presents the concept of operations and preliminary design of a multi-satellite
mission for the active removal of large pieces of debris from low Earth orbit. The mission …

It is now well realized [1] that two unstable dynamical systems, attempting to stabilize each
other using the error between their outputs for adjusting their parameters, may not always …

T stability of dynamically networked formations is at the heart of the science of autonomy. It is
paramount for the system to have the ability to detect unstable interactions early and …

The dynamic stability of a swarm is an essential consideration in the design of autonomous
formation flying spacecraft. In this paper, we begin by using an illustrative example to create …

We propose a new framework called Evolving Systems to describe the self-assembly, or
autonomous assembly, of actively controlled dynamical subsystems into an Evolved System …

Many systems must operate in the presence of delays both internal to the system and in its
inputs and outputs. In this paper we present a new robustness result for nonlinear systems …

The dynamic stability of autonomous agent formations is essential in understanding the
limitations of the formation and methods to restore any lack of stability. These formations can …

The dynamic stability of formation geometry is vital to the design of large scale multi-agent
systems. In this paper, we probe into the structure of the formation system matrix using the …

This paper is focused on adaptively controlling a linear infinite-dimensional system to cause
it to regulate the output to zero in the presence of persistent disturbances. The plant (A, B, C) …

New theory is presented for evolving systems, which are autonomously controlled
subsystems that self-assemble into a new evolved system with a higher purpose. Evolving …
