WirelessHART networks are gaining ground as a real-time communication infrastructure in industrial wireless control systems. Because wireless communication is often susceptible to transmission failures in industrial environments, it is essential to account for failures in the delay analysis for realtime flows between sensors and actuators in process control. WirelessHART networks handle transmi...

This paper is concerned with the coordinated formation control problem of multiple autonomous underwater vehicles (AUVs) under alterable communication topology and time-varying delay in discrete time domain. Firstly, multi-AUV system divided into one leader followers, two parts. The coupled nonlinear AUV model linearized a second-order integral using state feedback. Secondly, types controllers ...

The Wireless Sensor Networks (WSN) particularly for real time applications raise fundamental problems for the scientific community. These problems are related to the limit of energy resource and the real time constraints on the communication delay. The well functioning of such networks depends mainly on the network lifetime result of nodes energies and the communication delay which should meet ...

In this paper we have addressed the delay problem for real time control system. Real time control systems response is critical for any abnormal condition. We have modeled a communication and control system for system delay by using dymonda software that describes both the system hardware and software conditions. We have programmed an echo server and client application on VMware player for a par...

An adaptive algorithm is introduced in this paper to estimate random communication time delay in Networked Control Systems (NCS). The algorithm updates an adaptive delay estimate using gradient descent method, and identifies plant parameters by a modified RLS. By using this algorithm, future control sequences are generated to compensate for the communication time delay when control signals are ...

oro-antral communication and fistula can occur as a result of inadequate and improper treatment. inadvertent communication with the maxillary sinus can occur during certain surgical procedures in the maxillary posterior region. though, spontaneous healing may occur in defects which are smaller than 2 mm but larger communications require immediate attention and should be treated without delay, i...

In this paper, a novel structure for a communication disturbance observer in teleoperation systems is proposed to achieve robust stability. A time delay compensation method based on the concept of network disturbance and a communication disturbance observer (CDOB) has been proposed in past research. Unlike model-based approaches, it works without a time delay model. Therefore, it can be impleme...

This paper addresses the problem of time-varying communication delay in force reflecting bilateral teleoperation. The problem is motivated by the increasing use of the Internet as a communication medium where the time delay is variable depending on factors such as congestion, bandwidth, or distance. The well-known scattering formalism introduced in [1] preserves passivity of the communication c...
