Lp stability of networked control systems implemented on WirelessHART

Improving simulation of wireless networked control systems based on WirelessHART

The scalability and flexibility of wireless networks are the basis of the growing success of Wireless Networked Control Systems (WNCSs). Both the HART Communication Foundation and the ISA association have recently proposed their own standard for a wireless fieldbus (WirelessHART ratified in 2007, and ISA100.11a ratified in 2009, respectively). However, WNCSs performances are hard to verify in t...

Emulation-based stabilization of networked control systems implemented on FlexRay

We investigate the emulation controller design approach for nonlinear networked control systems (NCS) with FlexRay. FlexRayis a deterministic communication protocol which is increasingly used in the automotive industry as it provides a high bandwidthand allows for safety critical applications. It is characterized by pre-set communication cycles that are subdivided into staticand dyn...

Stability and Stabilization of Networked Control Systems

The presence of a communication network in a control loop induces many imperfections such as varying transmission delays, varying sampling/transmission intervals, packet loss, communication constraints and quantization effects, which can degrade the control performance significantly and even lead to instability. Various techniques have been proposed in the literature for stability analysis and ...

Stability analysis of networked control systems

Gregory C. Walsh and Hong Ye and Linda Bushnell1 Department of Mechanical Engineering University of Maryland at College Park, MD 20742 [email protected], [email protected] Abstract In this paper we introduce a novel control network protocol, Try-Once-Discard (TOD), for networked control systems (NCS), and provide, for the rst time, an analytic proof of global exponential stability for both th...
