Orientation: Whilst extensive literature is available on leadership, followership under-researched. This study, therefore, pays attention to specific follower behaviours that can influence the leadership process and are passive. Research purpose: study offers deeper insights into their process. Motivation for study: By extending original research in China of Carsten, Uhl-Bien Huang followership...

We consider the problem of having a team of nonholonomic mobile robots follow a desired leader-follower formation using omnidirectional vision. By specifying the desired formation in the image plane, we translate the control problem into a separate visual servoing task for each follower. We use a rank constraint on the omnidirectional optical flows across multiple frames to estimate the positio...

This paper studies the leader-follower formation control for multiple quadrotors. Two controllers are used. The first one is a proportional derivative controller used to ensure the tracking of the leader to the desired trajectory, while the second is based on fuzzy logic in order to achieve the desired formation in ! − ! plane with equal height (!) for all follower quadrotors. In order to ensur...

This article addresses the challenge of attitude synchronization a group rigid bodies (considered to be agents) with zero final angular velocity. A collaborative control strategy is proposed tackle this issue, using decentralized consensus within leader-follower scheme, and communication between agents activated by events. The parameterized unit quaternion. law incorporates an event function sp...

This paper is concerned with the analysis of a class of impacting systems of relevance in applications: cam-follower systems. We show that these systems, which can be modelled as discontinuously forced impact oscillators, can exhibit complex behaviour due to the detachment at high rotational speeds between the follower and the cam. We propose that the observed phenomena can be explained in term...

We study the performance of leader-follower noisy consensus networks, and in particular, the relationship between this performance and the locations of the leader nodes. Two types of dynamics are considered (1) noise-free leaders, in which leaders dictate the trajectory exactly and followers are subject to external disturbances, and (2) noise-corrupted leaders, in which both leaders and followe...

Large-scale networks of dynamical systems are becoming increasingly important in science and technology. These systems arise in a variety of applications ranging from social networks, power systems, and robotics. In modeling, analysis, and control of networked systems, it is of fundamental importance to understand the interplay between network structure and underlying dynamical properties. My r...

This paper deals with the stability analysis of a class of uncertain switched systems on nonuniform timedomains. The considered class consists of dynamical systemswhich commute between an uncertain continuous-time subsystem and an uncertain discrete-time subsystem during a certain period of time. The theory of dynamic equations on time scale is used to study the stability of these systems on no...

Cooperative regulation of multiagent systems has become an active research area in the past decade. This paper reviews some recent progress in distributed coordination control for leader-following multiagent systems and its applications in power system and mainly focuses on the cooperative tracking control in terms of consensus tracking control and containment tracking control. Next, methods on...

In this paper we aim to address the problem of dynamically dispatching a group of state-of-the-art deloaded wind generators (WGs) in a fair-sharing manner. We use the term dynamically since the WGs aim to dispatch themselves according to a varying committed WF power output. We first propose a leader-follower protocol whose execution guarantees asymptotically, two control objectives. These are 1...
