These days, networked control systems (NCSs) in which data is transmitted via communication have been actively studied for many potential applications. In an NCS, dropout degrades performance depending on network conditions. For NCS with dropout, the authors propose a model-predictive-control-based input optimisation, representing as both Bernoulli model and finite-order Markov chain. Using pro...

This paper will propose the state feedback control based networked control system (NCS) design with the differential evolution algorithm. For designing a networked control system, one has to overcome the problems about the random latency and the data packet dropouts. Here, we will apply the state feedback control theory to design a controller to overcome the random latency and the data packet d...

Abstract: In the networked control system (NCS), the uncertain network-induced delay and nonlinear controlled object are the main problems, because they can degrade the performance of the control system and even destabilize it. In this paper, a class of uncertain and nonlinear networked control systems is discussed and its sufficient condition for the robust asymptotic stability is presented. F...

Networked Control Systems (NCS) are distributed systems where plants, sensors, actuators and controllers communicate over shared networks. Non-ideal behaviors of the communication network include variable sampling/transmission intervals and communication delays, packet losses, communication constraints and quantization errors. NCS have been the object of intensive study in the last few years. H...

In networked control systems (NCS), it is considered essential to design a robust controller such that the networked-system is stable against data dropouts during the network transfer. It has been shown that there is a critical data dropout rate over which the networkedsystem could be unstable; hence the desired task cannot be achieved. This paper shows that a desired task or trajectories can b...

The paper under discussion [12] presents the analytical results underlying the authors’ design of a networked control system (NCS) operating over a cellular network. Their formulation fits the common framework [7, 14], in which there are transmission delays present in the sensor/controller and controller/actuator paths. One key difference between this work and existing literature relates to the...

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...

This paper introduces a new definition of stochastic protocols for networked control systems (NCS) and the stochastic analogue of the notion of uniform persistency of excitation of protocols first presented in [1]. Our framework applies directly to common wireless and wireline NCS, including those built on collision-sense multiple access (CSMA) style protocols, with Ethernet and 802.11a/b/g as ...

This paper is concerned with the stabilization problem for networked control systems (NCSs) with packet-dropouts and delays. A state estimator is incorporated into the controller node, and the controller uses the estimated states when packet-dropouts occur. By using such a estimator-based controller, the closed-loop NCS is modelled as a discrete-time switched systems with both stable and unstab...

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...
