Self-Triggered Coverage Control for Mobile Sensors
IEEE Transactions on Robotics, 2023The deployment and coordination of mobile sensor networks for coverage control applications can present several practical challenges including how to efficiently share limited communication resources and how to reduce the use of localization devices (e.g., radars and lidars).

Self-triggered channel ion source
Review of Scientific Instruments, 1979An ion source made from a continuous dynode electron multiplier of the straight channel type and an ion reflector device is described. Its principle of operation is based on a continuous self-sustained ion and electron cascade in the multiplier channel. Operating characteristics and the analysis of the ions produced are presented.

Self-triggered pursuit of a single evader
2015 54th IEEE Conference on Decision and Control (CDC), 2015This paper studies a continuous-time pursuit-evasion problem involving a single pursuer and a single evader on a plane. In contrast to other works that study this problem, we are interested in developing a pursuit strategy that doesn't require continuous, or even periodic, information about the position of the evader.

Isochronous manifolds in self-triggered control
Proceedings of the 48h IEEE Conference on Decision and Control (CDC) held jointly with 2009 28th Chinese Control Conference, 2009Feedback control laws are predominantly implemented on digital platforms as periodic tasks. Although periodicity simplifies the analysis and design of the implementation, new applications call for more efficient utilization of available resources such as processor utilization. To address this issue, new implementation paradigms, such as event-triggered

Optimal-sampling-inspired Self-Triggered control
2015 International Conference on Event-based Control, Communication, and Signal Processing (EBCCSP), 2015Self-triggered control is an appealing sampling strategy that promises to preserve the same control performance as traditional (periodic) sampling, yet consuming less computing resource by executing the controller less frequently. While the stability of self-triggered controllers is often addressed, their capacity to actually reduce the cost is more ...

Self-triggered linear quadratic Networked Control
2012 20th Mediterranean Conference on Control & Automation (MED), 2012SUMMARYThis paper deals with networked control systems design, under the constraint of limited bandwidth on the communication channel. A linear quadratic problem for a fixed sampling period is solved, and this result is used for the development of and performance indexes, yielding to the statement and solution of and optimal control problems ...

On self-triggered synchronization of linear systems
IFAC Proceedings Volumes, 2013Abstract Synchronization is one of the basic problems in coordinated control. The standard underlying assumption is that the systems that aim at synchronizing exchange information continuously. However, the real-time implementation of coordinating algorithms poses severe constraints on the amount and the schedule of exchanged information.

Active target tracking with self-triggered communications
2017 IEEE International Conference on Robotics and Automation (ICRA), 2017We study the problem of reducing the amount of communication in a distributed target tracking problem. We focus on the scenario where a team of robots are allowed to move on the boundary of the environment. Their goal is to seek a formation so as to best track a target moving in the interior of the environment.

Self-triggered stabilization of homogeneous control systems
2008 American Control Conference, 2008Digital implementations of feedback laws commonly consider periodic execution of control tasks. In this paper we go beyond the periodic model by developing self-triggered schedules for the execution of control tasks. These schedules guarantee asymptotic stability under sample-and-hold implementations while drastically reducing processor usage when ...

Self-triggered control for the stabilization of linear systems
2012 9th International Conference on Electrical Engineering, Computing Science and Automatic Control (CCE), 2012Contrary to the classical (time-triggered) principle that samples the system states and calculates the control signal in a periodic fashion, a self-triggered control predicts the next time at which the states must be sampled and the control signal updated and applied. The main advantage of self-triggered control implementation is that it eliminates the
