In the research on the networked control systems (NCS) the performance of the control system is assumed to be affected by network induced parameters such as delays, jitters, packet losses, link failures. In this paper a reconfiguration of the network control is presented. The upper bound delay of the transmission time of a packet is monitored with the network calculus based algorithm. A modific...

This paper considers the event-triggered control problem for a class of Networked Control Systems (NCS) subject to transmission delays and stochastic deception attacks. A new fuzzy weighted memory mechanism is proposed reduce network bandwidth consumption data rates. In this context, state feedback controller stabilize closed-loop NCS. Considering security NCS, randomly occurring attack model e...

T HE accelerated integration and convergence of communications , computing, and control over the last decade has inspired researchers and practitioners from a variety of disciplines to become interested in the emerging field of networked control systems (NCS). In general, an NCS consists of sensors, actua-tors, and controllers whose operations are distributed at different geographical locations...

Based on discrete event-triggered communication scheme (DETCS), this paper is concerned with the satisfactory H ! / H 2 event-triggered fault-tolerant control problem for networked control system (NCS) with α -safety degree and actuator saturation constraint from the perspective of improving satisfaction of fault-tolerant control and saving network resource. Firstly, the closed-loop NCS model w...

This paper deals with the co-design of a Network Control System (NCS) and its diagnosis. Residuals are shown to be affected by network packet losses. A new indicator, sensitive to packet losses is proposed and thus changes in the residuals due to faults or to packet losses can be differentiated. Results are exemplified through the simulation of a 4-rotor helicopter using the Matlab/Simulink sta...

T INT raditional centralized control architectures where a supervisory controller directly interfaces in a point-to-point fashion with all sensors and actuators in the system have been successfully implemented in the past. They are generally feasible when a controller interfaces with small number of sensors and actuators and requires short wiring to them. However, it is often difficult to add, ...

Distributed applications require information to effectively utilize the network. Some of the information they require is the current and maximum bandwidth, current and minimum latency, bottlenecks, burst frequency, and congestion extent. This type of information allows applications to determine parameters like optimal TCP buffer size. In this paper, we present a cooperative information-gatherin...

Networked control systems (NCS) are spatially-distributed systems in which communication between sensors, controllers, and actuators is supported by a shared communication network that is subject to variable communication delays, quantization errors, packet losses, limited bandwidth, and other practical non-idealities. This work investigates the problem of constructively deriving symbolic model...

The stability and performance of a networked control system (NCS) strongly depends on the transmission delay. However, the randomness of the transmission delay is an intrinsic property in the network communication, e.g. Ethernet. Aiming at NCS with random transmission delay, a novel control approach is proposed. The transmission delays from sensorto-controller (SC) and controller-to-actuator (C...

This paper presents a practical network platform to design and implement a networked-based cascade control system linking a Smar Foundation Fieldbus (FF) controller (DFI-302) and a Siemens programmable logic controller (PLC-S7-315-2DP) through Industrial Ethernet to a laboratory pilot plant. In the presented network configuration, the Smar OPC tag browser and Siemens WinCC OPC Channel provide t...
