Distance-based control of formations with orientation control
2015 54th IEEE Conference on Decision and Control (CDC), 2015In this paper, we deal with formation stabilization of a group of mobile agents with orientation control. The proposed method is to combine usual distance-based control with displacement-based control so that the shape of the formation is dominantly controlled by distance-based control, and the orientation of the whole formation is forced to converge ...

On Control for Agents Formation
2007Agents control has a broad spectrum of applications in computer science, communications and robotics. This paper focuses on formation of mobile agents, that is, configuration of points in the plane without kinematic restrictions of motion. Several goal formation strategies may be of interest.

Genetic Control of Bone Formation
Annual Review of Cell and Developmental Biology, 2009In the past few years, our molecular understanding of bone formation has continued to increase. This review aims to present a comprehensive view of the current state of knowledge in the field. Thus, it will cover our current knowledge of chondrogenesis and osteoblastogenesis. It will also cover the most salient aspects of osteoblast function.

Retraction balancing and formation control
2015 54th IEEE Conference on Decision and Control (CDC), 2015We consider a formation control problem in which a collection of systems is ought to attain a balanced configuration on a submanifold of their state space. The submanifold thus determines the shape and position of the desired formation. We solve the formation control problem by simultaneously balancing the retractions of the systems onto the ...

Controlling Microdroplet Formation by Light
Langmuir, 1998A surface with photocontrollable wetting behavior is introduced. A monolayer of a polymeric material containing 4‘-[trifluormethoxy-4,4‘-dibenzoazo] dyes in the side chains has been transferred on ...

Geometry and control of satellite formations
Proceedings of the 2000 American Control Conference. ACC (IEEE Cat. No.00CH36334), 2000Satellite formations based on the solutions to Hill's equations have relatively simple geometric shapes. This paper shows that all such formations around a leader satellite in a circular orbit are determined by the intersection of a plane and an elliptic cylinder of eccentricity /spl radic/3/2. In a moving coordinate system fixed to the leader.

Formation control with collision avoidance
IEEE Conference on Decision and Control and European Control Conference, 2011We present a formation flight control strategy featuring a collision avoidance scheme. The control algorithm is based on a Sliding Mode controller. The controller sliding surfaces account for aircraft maneuvering limitations, restricting the required velocities to a feasible set.

Remarks on ISS and formation control
2004 43rd IEEE Conference on Decision and Control (CDC) (IEEE Cat. No.04CH37601), 2004For a leader/follower formation of autonomous mobile agents, the concept of input-to-state stability has been proposed recently as a valid tool to relate the influence of the motion of the leader to the formation error. The ISS approach is quite promising, as it allows great flexibility in the formation topology, and yields computable gains relating ...

Formation control of robotic vehicles
2005 IEEE International Conference on Robotics and Biomimetics - ROBIO, 2005In this paper, the problem of formation control of robotic vehicles is studied. For a general formation (path, tree, or net) with one leader, a decentralized controller is proposed that yields exponential stability of the formation.

TURBULENCE CONTROL AND SYNCHRONIZATION AND CONTROLLABLE PATTERN FORMATION
International Journal of Bifurcation and Chaos, 2000Pattern and turbulence control and synchronization are investigated by considering the model of the complex Ginzburg–Landau equation. It is shown that in fully-developed turbulence region, when a large number of positive Lyapunov exponents exists, in the presence of a large gradient force, we can drive the system to various desired spatiotemporal ...
