Current advances in processor technology and the rapid development of high-speed networking technology (e.g., Asynchronous Transfer Mode (ATM), Myrinet, and Fast Ethernet) have made network-based computing an attractive environment for large-scale High Performance Distributed Computing (HPDC) applications. However, due to the communication overhead between computers and the in exible communicat...

Network control system (NCS) has higher requirements on QoS index of the network, but MANET can hardly meet the demands of control systems because of its own characteristics. The paper improves AODV and proposes AODV routing protocol QAODV with certain QoS security in combination with NCS and MANET, and expounds routing detection, routing register and routing maintenance. Simulation results sho...

Real-Time Control Over Networks. (May 2006) Kun Ji, B. S., Tsinghua University, Beijing, China; M. S., Tsinghua University, Beijing, China Chair of Advisory Committee: Dr. Won-jong Kim A control system in which sensors, actuators, and controllers are interconnected over a communication network is called a networked control system (NCS). Enhanced computational capabilities and bandwidths in the ...

The Networked Control System in modern control widely uses to decrease the implementation cost and increasing the performance. NCS in addition to its advantages is inevitable. Nevertheless they suffer of some limitations and deficiencies. Packet loss is one of the main limitations which affect the control system in different conditions and finally may lead to system instability. For this reason...

A recent study shows that a given hierarchical decentralized control system architecture may be suitable for autonomous coordination of fault-tolerant control (FTC) in a network of distributed and interconnected subsystems. This paper focuses on the development of a robust Fault Detection and Isolation (FDI) strategy for this Network Control System (NCS) FTC problem. By using a robust form of t...

In this paper the effects of quantization in an important class of networked control systems called model-based networked control systems (MB-NCS) are considered. The MB-NCS architecture uses an explicit model of the plant in the controller in order to reduce the network traffic, while attempting to prevent excessive performance degradation. Sufficient stability conditions for two types of stat...

Optimization-based approach to cross-layer resource management in Wireless networked control systems Report Title Wireless Networked Control Systems (NCS) are increasingly deployed to monitor and control Cyber-Physical Systems (CPS), as wireless network provides great convenience in terms of fully mobile operation, rapid deployment and flexible installation. To support mission critical operatio...

This paper presents results of modelling and analysis of Network Control Systems (NCS) using the reconfiguration strategies in case of individual networks faults. In general the NCS as all systems follows its mission which should be accomplished with guarantee. The system mission can be disturbed or interrupted by failures which occur with some probability. A primary requirement in order to ben...

This work presents a method to estimate an unknown varying delay of measurements and subsequent Kalman filtering in the networked control system (NCS) framework. The delay estimation algorithm is based on the Gaussian error model and a network delay model, either a probability distribution or a Markov-chain. This method is used to tackle the problem with varying delays in a NCS. The undelayed o...

Aims: Though Networked Control Systems (NCS) have great benefits, such as remote control, low costs, and better flexibility, it also has several drawbacks network-induced time delay packet loss, which may result in performance degradation system instability nonlinear systems. This paper proposes a gain scheduling Proportional-Integral-Differential (GS-PID) controller design to address the issue...
