Distributed tracking control of leader-follower multi-agent systems under noisy measurement

In this paper, a distributed tracking control scheme with distributed estimators has been developed for a leader-follower multi-agent system with measurement noises and directed interconnection topology. It is supposed that each follower can only measure relative positions of its neighbors in a noisy environment, including the relative position of the second-order active leader. A neighbor-based tracking protocol together with distributed estimators is designed based on a novel velocity decomposition technique. It is shown that the closed loop tracking control system is stochastically stable in mean square and the estimation errors converge to zero in mean square as well. A simulation example is finally given to illustrate the performance of the proposed control scheme.Comment: 8 Pages, 3 figure

Horses

Neith Nevelson (1946-2023) was a significant figure in the Coconut Grove arts scene, and Miami’s broader bohemian arts community. She was the granddaughter of famed New York sculptor Louise Nevelson and through her she became friends with the likes of Salvador Dalí and Jasper Johns. She was raised in New York City visiting her grandmother’s studio, and later studied fine art in Florence. Her style is loosely Neoexpressionist, and often used unconventional and experimental materials and application methods. Nevelson’s most recognizable series of work were her Nudes, Horses, and Faces/Masks. Her career was covered on television as well as major print media and her patrons included Marta Permuy. This piece is from her Horses, among her longest running and most established series.The series shows her innate need for freedom, as well as nodding to her equestrian hobbies in Europe during her youth.https://nsuworks.nova.edu/nsudigital_permuycollection/1006/thumbnail.jp
