This paper addresses energy-aware control in a wireless control system. The goal is to save energy in a smart sensor node by codesigning its use of the radio chip together with the control policy. The focus is on exploiting the fact that in many radio chips used in wireless nodes the depth of sleep can be manipulated dynamically. The choice of the mode involves a tradeoff, since deeper sleep is cheaper...
This paper proposes an event-based scheme to control a networked control system and to manage the radio-modes of its smart sensor node. The smart node is battery driven and is in charge of sensing the system and computing the control law which is sent to the receiver using a wireless channel. To save energy and to limit the amount of communication with the receiver, the smart node combines two techniques:...
Energy efficiency is one of the main issues in wireless Networked Control Systems. The control community has already shown large interest in the topics of intermittent control and event-based control, allowing to turn off the radio of the nodes, which is the main energy consumer, on longer time intervals than in the periodic case. While the existing literature only addresses policies using two radio-modes...
