The current trend in the development of Networked Control Systems (NCS) is the use of wireless networks to communicate the system nodes, which have been called Wireless Sensors and Actuators Networks (WSAN). This trend is principally to increase flexibility and reliability of these applications and to reduce the implementation cost. Several protocols have been used, however the latency and jitt...

In this paper, we consider a networked control system (NCS) in which an dynamic plant system is connected to a controller via a temporally correlated wireless fading channel. We focus on communication power design at the sensor to minimize a weighted average state estimation error at the remote controller subject to an average transmit power constraint of the sensor. The power control optimizat...

“Networked control system” (NCS) is an umbrella term encompassing a broad variety of infrastructures such as industrial control systems (ICSs) and building automation systems (BASs). Nowadays, all these infrastructures play an important role in several aspects of our daily life, from managing essential services such as energy and water (e.g., critical infrastructures) to monitoring the increasi...

In this chapter, a class of discrete time uncertain linear hybrid systems, affected by both parameter variations and exterior disturbances, is considered. The main question is whether there exists a controller such that the closed loop system exhibits desired behavior under dynamic uncertainty and exterior disturbances. The notion of attainability is introduced to refer to the specified behavio...

We consider a networked control system (NCS) with packet loss being modeled as a stochastic process. We focus on the stochastic H∞ control approach. The designed controller is dynamic in the sense that it depends on the behavior of the lossy channel. First we apply the existing result on H∞ approach for NCS [4] to a teleoperating system. The fixed loss probability assumption in this result has ...

This paper is concerned with the research on fault tolerant control (FTC) of networked control system (NCS) with fixed data packet loss rate (PLR). A synthetic model of the whole closed-loop is presented which includes time delay, packet loss of NCS and the working condition of sensors and actuators. The time delay is supposed to be shorter than sampling period and packet loss to be random but ...

The use of avionics networks for flight control system results in a reduced aircraft weight, system installation, integration and maintenance costs as well as an improved airborne system performance and flexibility. This paper studies the stability and control design problems with performance analysis for networked flight control systems (NFCS) with random time delays by modeling NFCS as a disc...

Taking a network QoS designer’s point of view, this paper firstly reviews some of the recent advances on the NCS (Networked Control Systems) design then analyzes its requirements in terms of network QoS guarantees and its capacity to tolerate network performance variation. Current deterministic QoS design approach (including traffic schedulability analysis) may lead to network resource overprov...

A networked control system (NCS) is a control system in which plants, sensors, controllers, and actuators are connected through communication networks. In this paper, as one of the design problems for NCSs, we consider optimal sampled-data control of linear systems with uncertain input delay and uncertain sampling period. First, an input delay system is transformed into a discrete-time system w...

High Performance Distributed Computing (HPDC) applications require low-latency and high-throughput communication services and HPDC applications have diierent Quality of Service (QOS) requirements (e.g., bandwidth requirement, ow/error control algorithms, etc.). The communication services provided by traditional message-passing systems are xed and thus can not be changed to meet the requirements...
