Time-varying formation control for mobile robots: Algorithms and experiments

IECON 2017 - 43rd Annual Conference of the IEEE Industrial Electronics Society, 2017
Time-varying formation control problems for mobile robot swarm systems are investigated. Firstly, for the formation control, the mobile robot is regarded as a point-mass system, and the dynamics of each mobile robot is modeled by single integrator. Then, consensus-based formation protocols are presented for mobile robots to achieve a predefined time ...

Smooth Time-Varying Formation Control of Multiple Nonholonomic Agents

2015
In this paper, we investigate the position/orientation formation problem of multiple nonholonomic agents. Coordinate transformations are first presented to obtain the matrix form of formation error model, then a distributed smooth time-varying control law is designed based on a Lyapunov-like function.

Flexible Formation Control through Time-Varying Weighting Multi-Agent Flocking

2019 Chinese Control And Decision Conference (CCDC), 2019
This paper deals with flexible (or time-varying) formation control problems of second-order integral multi-agent networks. Flexible formation control is achieved by exploiting a time-varying weighting flocking control approach. Formation existence and basic features under the generalized time-varying flocking algorithm are investigated, including ...

Dynamically controlled excitation source for a time-varying format synthesizer

ICASSP '86. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
In this paper, we briefly study the effects of source-tract interaction on the waveshape of real glottal pulses. We simulate these effects in an formant synthesizer by using a dynamic variation of the voiced excitation and periodically time-varying formant filters.

Control of triangular formations with a time-varying scale function

Proceedings of the 2011 American Control Conference, 2011
This paper considers a novel problem of how to choose the scale of the final geometry for three agents in a triangular formation. Instead of assigning a set of desired side lengths, here the only requirement for the desired geometry is a triangle without any location, rotation and, most importantly, scale constraints.

Time-varying formation control for swarm systems with communication constraints

2018 37th Chinese Control Conference (CCC), 2018
Time-varying formation analysis and design problems for high-order swarm systems with communication constraints are investigated. Firstly, a time-varying formation control protocol is proposed only using intermittent relative local information. Then, sufficient conditions for time-varying formation analysis and design are given by linear matrix ...

Time-varying formation control for general linear multi-agent systems with time-varying delays and switching topologies

2018 IEEE 14th International Conference on Control and Automation (ICCA), 2018
Time-varying formation control problems for general linear multi-agent systems with switching interaction topologies and time-varying delays are investigated. Firstly, a consensus based control protocol is proposed using local neighboring information. An algorithm with three steps is presented to design the formation control protocol. Then using common

Quad-Rotor robust time-varying formation control: a Continuous Sliding-Mode Control approach

International Journal of Control, 2018
This paper deals with the robust tracking problem for a group of Quad-Rotors forming a time-varying geometric pattern, i.e. formation control, in the presence of external disturbances.

Distributed Event‐Triggered Time‐Varying Formation Control Under Multiplicative Noises

International Journal of Robust and Nonlinear Control
ABSTRACTThis paper investigates the distributed event‐triggered time‐varying formation (DETTVF) control problem of linear multiagent systems (MASs) that are subject to some multiplicative measurement noises in uncertain communication settings. A static‐gain DETTVF control protocol is first designed, together with a new triggering mechanism, to cope ...
