چکیده

The problem of self-tuning of coupling parameters in multi-agent systems is considered. Agent dynamics are described by a discrete-time double integrator with unknown input gain. Each agent locally tunes the strength of interaction with neighboring agents by using a normalized gradient algorithm (NGA). The tuning algorithm minimizes the square of the error between an individual agent’s state (velocity) and the one step delayed average of its own state and the states of its neighbors. Assuming that the network graph is strongly connected, it is proved that the sequence of coupling parameters is convergent and all velocities converge toward the same constant value. © 2014 Elsevier B.V.

Accelerating Approximate Consensus with Self-Organizing Overlays

Laplacian-based approximate consensus algorithms are an important and frequently used building block in many distributed applications, including formation control, sensor fusion, and synchronization. These algorithms, however, converge extremely slowly on networks that are more than a few hops in diameter and where values are spatially correlated. This paper presents a new algorithm, Power Law ...

The consensus algorithm for the distributed clocks synchronization

In this talk we will first describe how the clocks synchronization problem can be modeled as a consensus algorithm for heterogeneous double integrators. We show two possible implementations of this consensus based clocks synchronization. The dynamics of one of these can be described as a discrete time nonlinear system, which is a perturbation of the linear system. Hence, using the center manifo...
