The leader–follower consensus of a class variable-order fractional (VOF) uncertain linear multi-agent systems is studied in this paper. Firstly, new general lemma proposed to find Lyapunov candidate functions for the stability VOF systems. Secondly, according and theorem systems, by using singular value decomposition matrices some related lemmas, sufficient condition obtain given form matrix in...

This paper addresses the distributed consensus design problem for linear multi-agent systems with directed communication graphs and external disturbances. Both the cases with strongly connected communication graphs and leader-follower graphs containing a directed spanning tree with the leader as the root are discussed. Distributed adaptive consensus protocols based on the relative states of nei...

Robot technology has recently been applied to many applications help human activities. Mobile is one of the most flexible robot technology. This research uses a mobile designed using an omnidirectional wheel for movement mechanism. Coordination and control multi-robots can be assigned perform any task from different kind field. Therefore, this paper aims develop multi-robot system form formatio...

In this paper, the important formation control problem of nonholonomic wheeled mobile robots is investigated via a leader-follower strategy. To this end, the dynamics model of the considered wheeled mobile robot is derived using Lagrange equations of motion. Then, using ADAMS multi-body simulation software, the obtained dynamics of the wheeled system in MATLAB software is verified. After that, ...

The aim of this study was to design a navigation system composed of a human-controlled leader vehicle and a follower vehicle. The follower vehicle automatically tracks the leader vehicle. With such a system, a human driver can control two vehicles efficiently in agricultural operations. The tracking system was developed for the leader and the follower vehicle, and control of the follower was pe...

Innovation, and the creative thinking that provides basis for innovation, is of great value organizations. In this article we describe what needed people to think creatively, noting a complex, albeit voluntary, activity involving performance on certain types problems. The ways leaders influence peoples’ willingness engage in, ability solve, problems are then described. Leaders efforts must not ...

Extensions of a consensus algorithm are introduced for systems modelled by second-order dynamics. Variants of those consensus algorithms are applied to tackle formation control problems by appropriately choosing information states on which consensus is reached. Even in the absence of centralised leadership, the consensus-based formation control strategies can guarantee accurate formation mainte...

We examine the characteristics of effective leaders in a simple leader-follower voluntary contributions game. We focus on two factors: the individual’s cooperativeness and the individual’s beliefs about the cooperativeness of others. We find that groups perform best when led by those who are cooperatively inclined. Partly, this reflects a false consensus effect: cooperative leaders are more opt...

This paper addresses the distributed consensus protocol design problem for linear multi-agent systems with directed graphs and external unmatched disturbances. A novel distributed adaptive consensus protocol is proposed to achieve leader-follower consensus for any directed graph containing a directed spanning tree with the leader as the root node. It is noted that the adaptive protocol might su...
