To overcome sluggish load disturbance response for industrial/chemical processes with slow time constant(s), an improved design for on-line autotuning of proportional-integral-derivative (PID) controller is proposed in this paper, based on relay identification of the widely used first-order-plus-dead-time (FOPDT) process model.
Based on relay functionality of D2D communications, literature [19] proposes an approach to extend battery life, where the main objective is to help UEs with a low-battery level to save energy by relaying its data, and the relaying UE is selected according to the metric of the neighbors' remaining battery and distance.
Spectrum sharing protocols based on amplify-and-forward relaying in Rayleigh and Nakagami-m fading were studied in [27, 28], and the outage performances of the protocols based on relay selection in Rayleigh and Nakagami-m fading were studied in [29, 30], respectively.
A modification of vector control principle is designed on the base of new relay control law, which is used for generation of damping oscillating modes with unlimited growth in oscillation frequency.
A threshold based relay selection scheme is considered, in which the reliable relays are determined by comparing source-relay SNR to a threshold, and one of the reliable relays is selected by the destination based on relay-destination SNR.
Load flow and short circuit are input for formulation of rule base for implementation of relay coordination scheme in such protection techniques.
The intelligent deployment assumption is based on cost comparison studies of relay based and BS only deployments.
a Note that the TNs considered here can be can be represented as a set of base stations, relay nodes, femtocells, or users or a combination of different kinds of access nodes.
As evident from the nature of relay based MAC protocols, we use control packets to coordinate relays which are followed by the data and Acknowledgement (ACK) packets.
A solution to address this issue comes from the advent of cooperative communication [1, 2] in the form of relay based MAC protocols.
In [7] authors have used Markov chain model of [8] to show the energy consumption of relay based ad hoc networks.
