This paper is concerned with generalized predictive control based on state-space model for networked control systems. Both the network-induced time delay and packet loss are taken into account. The networked predictive controller design is discussed with respect to three network cases, which are related to packet loss, network-induced delay, and both packet loss and network-induced delay, respe...
providing a high-quality service for transmission and playing real-time voice conversations (voice streaming) over wireless ad-hoc networks is no mean feat. buffering together with adjusting the playout time of the packets is a receiver-side solution to overcome this challenge. in this paper, a new adaptive playout adjustment algorithm is proposed to stream the voice conversations over wireless...
in this study, a robust controller is designed for fuzzy network control systems (ncss) using the static output feedback. delay and data packet dropout affect on the stability of network control systems, and therefore, the asymptotic stability condition is established considering delay and data packet dropout. delay is time-varying while the lower and upper bounds for delay is defined, and the ...
Control systems with digital communication between sensors, controllers and actuators are called as Networked Control Systems (NCSs). In general, NCSs encounter with some problems such as packet dropouts and network induced delays. When plant uncertainty is added to the aforementioned problems, the design of the robust controller that is able to guarantee the stability, becomes more complex. In...
Networked control systems (NCSs) are distributed control systems in which the nodes, including controllers, sensors, actuators, and plants are connected by a digital communication network such as the Internet. One of the most critical challenges in networked control systems is the stochastic time delay of arriving data packets in the communication network among the nodes. Using the Smith predic...
Abstract Vehicular Ad Hoc Network (VANET) is a particular type of mobile ad hoc network in which vehicles communicate between themselves using wireless antenna. Due to unique characteristics of VANETs (e.g. high mobility of nodes and dynamic topology), routing is one of the challenging tasks in such networks. Consequently, delay tolerant networks which consider the disconnect nature of...
This article investigates a formation control problem of mobile robots. Two main issues of the formation control problem are addressed; one is the implementation of distributed formation control and another is the analysis of effect of network communication on the closed-loop systems. The distributed formation control is obtained by modelling the formation control problem as a linear-quadratic ...
In this study, we used the ARIMA time series model, the fuzzy-neural inference network, multi-layer perceptron artificial neural network, and ARIMA-ANN, ARIMA-ANFIS hybrid models for the modeling and prediction of the daily electrical conductivity parameter of daily teleZang hydrometric station over the statistical period of 49 years. For this purpose, the daily data for the 1996-2004 period we...
Time varying network induced delays in networked control systems (NCS) are known for degrading control system’s quality of performance (QoP) and causing stability problems. In literature, a control method employing modeling of communication delays as probability distribution, proves to be a better method. This paper focuses on modeling of network induced delays as probability distribution. CAN ...
