Leader-following coordination of multi-agent systems with coupling time delays

SummaryIn this paper, an adaptive fault-tolerant attitude coordinated tracking problem for spacecraft formation is investigated under a directed communication topology containing a spanning tree with the leader as the root, where inertia matrices and external disturbances are unknown time-varying. With no prior knowledge of faults and inertia, an adaptive approach is proposed to reject the influence of disturbances and uncertainties. Meanwhile, combining with a consensus algorithm and graph theory, an adaptive fault-tolerant attitude synchronization tracking control law is presented to regulate the attitude to a common time-varying reference state. Aiming at optimizing the control law, a dynamic adjustment function is introduced to adjust the control gain according to the attitude tracking error. The effectiveness of the proposed control approach is demonstrated through simulation results.

A distributed dynamic output feedback control is designed by Scardovi and Sepulchre for the synchronization of a network of identical linear systems, known as agents in literature. The design is based on some mild conditions allowing switching topology. But it assumes that there is no time delay in signal transfer between the neighbouring agents. In this paper we extend their work to include known time delay in communications. Furthermore, our design has some special features: (a) the delay can be arbitrary and only need to be uniformly bounded by a constant, (b) the conditions that time delay should be the same and sufficiently small in some literature are not required here, and (c) no local buffer is required to store past data due to time-delay effect.

“…Due to the technological advances in communication and computation, distributed coordination of networks of dynamic agents has attracted several researchers in many fields in recent years and many results have been obtained in [1][2][3][4][5][6][7][8][9]. In real systems, information interchange between each agent is often associated with time delays and the network graph should be switching as communication links in a multi-agent system may experience failures or recons-tructions.…”

“…Among many of the researches, the consensus problem is one of the most widely studied issues which is that each agent updates its control input based on the information of its neighbors in such a way that all agents get to a common value in final. Leader-following multi agent consensus has been actively studied and get a series of splendid achievements [1][2][3]. In [1], Gang et al investigated distributed controller design for a leader-follower network with communication delays.…”

-This paper is devoted to the study of rotating consensus problem for leader-following multi-agent system with and without multiple time-delays in an elliptical orbit and both switching topology which is kept connected. We first define rotating consensus problem of leader-following multi-agent system in a circular orbit, and through the mapping relationship between ellipse and circular, extend rotating consensus problem to elliptical orbit. Then, we propose two new protocols for leader-following multi-agent system with and without multiple time-delays. The main results provide sufficient conditions for existence of rotating consensus for leader-following multi-agent with and without multiple time-delays in an elliptical orbit.. Simulations are provided to show the effectiveness of the obtained theoretical results.
