Abstract(s)
Network control systems (NCSs) are spatially distributed systems in which the communication between sensors,
actuators and controllers occurs through a shared band-limited digital communication network. However, the use of a
shared communication network, in contrast to using several dedicated independent connections, introduces new
challenges which are even more acute in large scale and dense networked control systems. In this paper we investigate a
recently introduced technique of gathering information from a dense sensor network to be used in networked control
applications. Obtaining efficiently an approximate interpolation of the sensed data is exploited as offering a good tradeoff
between accuracy in the measurement of the input signals and the delay to the actuation. These are important aspects
to take into account for the quality of control. We introduce a variation to the state-of-the-art algorithms which we
prove to perform relatively better because it takes into account the changes over time of the input signal within the
process of obtaining an approximate interpolation.
