Title: On the emergent behaviors of stochastic flocking models.

Abstract: We study stochastic alignment of the Justh-Krishnaprasad(J-K) model under the additive and multiplicative noises. Justh and Krishnaprasad proposed a planar Newtonian particle model for an ensemble of flocking agents moving with a unit speed, where the dynamics of the heading angles (of velocities) is governed by a generalized Kuramoto-type model with a communication weight. In this paper, we are interested in the random perturbation of the communication weight, which is represented by the additive and multiplicative noises.

[HYKE Seminar] Dynamics and control for multi-agent networked systems: A finite-difference approach

There will be a HYKE Seminar

Title: Dynamics and control for multi-agent networked systems: A finite-difference approach
Speaker: Dr.고동남 (University of Deusto, Spain)
Time: 2020 January 2nd, 9:00am~9:50am
Place: 27-116
Abstract:
We analyze the control properties of consensus models. Starting form the link between linear multi-agent systems and the spatial semi-discretization of parabolic equations, we compare the consensus model with the heat equation. The existing techniques for PDE control problems allow us to derive explicit estimates on the controllability and control cost. Our approach shows that the chain or circular network systems have the same properties as the 1D heat equation while we may extend it to the multi-dimensional or fractional type heat equations.
