With the continuing trend towards globalization and focusing on high value with low volume, the manufacturing system architecture is evolving from traditional centralised model to the distributed model and to the recent networked model. In the modern manufacturing environment, the manufacturing systems are in networked framework via a variety of networking communication systems integrating the ...

In this paper, a nonlinear system aiming at reducing the signal transmission rate in a networked control system is constructed by adding nonlinear constraints to a linear feedback control system. Its stability is investigated in detail. It turns out that this nonlinear system exhibits very interesting dynamical behaviors: in addition to local stability, its trajectories may converge to a nonori...

In this paper, we consider the state controllability of networked systems, where the network topology is directed and weighted and the nodes are higher-dimensional linear time-invariant (LTI) dynamical systems. We investigate how the network topology, the node-system dynamics, the external control inputs, and the inner interactions affect the controllability of a networked system, and show that...

Original scientific paper This paper proposes an approach for achieving fault tolerant control algorithm for a kind of networked control system which is fixed set-point control and with nonlinear plant. We firstly describe the nonlinear networked control system and linearize the model of the plant at the operating point, then construct a synthesis model of the whole system, which includes all r...

Networked control is concerned with feedback control systems in which feedback or control signals are transmitted over communication links or networks. This emerging area, which seeks to integrate control and communication theories, presents several fundamental differences and challenges unlike those found in conventional control. A fundamental question facing networked control system design is...

The network disturbance effect can be considered as either a perturbation or as a pure time delay for the exchanged signals. The network-induced time delay is one of the main challenges when a network is inserted in the feedback loops of a control system. In this paper, our objective is to improve the behavior of a Networked Control System (NCS) by analyzing the time-delay given that the decent...

The Networked Systems Measurement and Control (NSMC) Group in the Department of Computing Science, University of Glasgow, consists of 5 academics, 2 research associates and 8 research students. The department was rated 5 in RAE 2001. The group conducts research into architectures, models, algorithms, measurement, and control of networked/distributed systems. The group is especially interested i...
