this paper is concerned with the consensus tracking problem of high order mimo nonlinear multi-agent systems. the agents must follow a leader node in presence of unknown dynamics and uncertain external disturbances. the communication network topology of agents is assumed to be a fixed undirected graph. a distributed adaptive control method is proposed to solve the consensus problem utilizing re...

This paper proposes a new finite-time consensus tracking protocol for reaching the fast finite-time consensus tracking. The Lyapunov function method, algebra graph theory, and homogeneity with dilation are employed to obtain the convergence criteria. Numerical simulations show that compared with the traditional finite-time consensus tracking protocols, the proposed protocol can accelerate the c...

This paper addresses distributed multi-object tracking over a network of heterogeneous and geographically dispersed nodes with sensing, communication and processing capabilities. The main contribution is an approach to distributed multi-object estimation based on labeled Random Finite Sets (RFSs) and dynamic Bayesian inference, which enables the development of two novel consensus tracking filte...

We present a method for efficiently generating a representation of a multimodal posterior probability distribution. The technique combines ideas from RANSAC and particle filtering such that the 3D visual tracking problem can be partitioned into two levels, while maintaining multiple hypotheses throughout. A simple texture change-point detector finds multiple hypotheses for the position of image...

This paper studies a distributed consensus tracking control problem for a class of stochastic linear multi-agent systems subject to two types of attacks. The problem boils down to how to achieve robust consensus tracking of multi-agent systems with switching connected and disconnected directed topologies under attacks. The attacks on the edges instead of nodes lead to the loss of consensus trac...

We present a novel method for tracking multiple objects in video captured by a non-stationary camera. For low quality video, ransac estimation fails when the number of good matches shrinks below the minimum required to estimate the motion model. This paper extends ransac in the following ways: (a) Allowing multiple models of different complexity to be chosen at random; (b) Introducing a conditi...

This work examines several dynamical aspects of average consensus in mobile networks. The results herein allow consensus on general time-varying signals, and allow tracking analysis using standard frequency-domain techniques. Further, the frequency-domain analysis naturally inspires a robust small-gain version of the algorithm, which tolerates arbitrary non-uniform time delays. Finally, we show...
