Asynchronous Decentralized Event-triggered Control
نویسندگان
چکیده
In this paper we propose an approach to the implementation of controllers with decentralized strategies triggering controller updates. We consider set-ups with a central node in charge of the computation of the control commands, and a set of not co-located sensors providing measurements to the controller node. The solution we propose does not require measurements from the sensors to be synchronized in time. The sensors in our proposal providemeasurements in an aperiodicway triggered by local conditions. Furthermore, in the proposed implementation (most of) the communication between nodes requires only the exchange of one bit of information (per controller update), which could aid in reducing transmission delays and as a secondary effect result in fewer transmissions being triggered. © 2014 Elsevier Ltd.

Decentralized and Cooperative Multi-Sensor Multi-Target Tracking With Asynchronous Bearing Measurements
Bearings only tracking is a challenging issue with many applications in military and commercial areas. In distributed multi-sensor multi-target bearings only tracking, sensors are far from each other, but are exchanging data using telecommunication equipment. In addition to the general benefits of distributed systems, this tracking system has another important advantage: if the sensors are suff...
متن کاملDecentralised event-triggered cooperative control with limited communication
This note studies event-triggered control of Multi-Agent Systems (MAS) with first order integrator dynamics. It extends previous work on event-triggered consensus by considering limited communication capabilities through strict peer-to-peer non-continuous information exchange. The approach provides both a decentralized control law and a decentralized communication policy. Communication events r...
متن کاملDecentralized Event-Triggered Broadcasts over Networked Control Systems
This paper examines event-triggered broadcasting of state information in distributed networked systems. Event-triggering has the agent broadcast its state information when its local “error” signal exceeds a given threshold. We present a decentralized approach for determining event-triggering thresholds for nonlinear subsystems with the assumption that each agent only has access to its local sta...

We propose and analyze centralized and decentralized asynchronous control structures for the parametric optimization of stochastic discrete-event systems (DES) consisting of K distributed components. We use a stochastic approximation type of optimization scheme driven by gradient estimates of a global performance measure with respect to local control parameters. The estimates are obtained in di...
