In this paper we study the effect of external perturbations on a networked control system. We start by assuming that the nonnetworked system without perturbation is exponentially stable. Then, for fast enough networks we show that if the perturbation is bounded the networked system is ultimately bounded and if the perturbation is vanishing then the networked system is asymptotically stable. We ...

This paper has proposed a controller design method for networked control systems with network induced delays by using LMI-based delay-dependent optimization. The delays are described by a Markov chain, since they are to be time-varying and even longer than the sampling time. A delay-dependent compensation method has been proposed here with a jump linear system analysis technique to stabilize th...

We believe that a standard control software framework which enables rapid, reliable and evolvable application development is the key for the proliferation of the networked control systems. Accordingly, we have been working on developing a domainware for general purpose control system, called Etherware. Even though Etherware supports many of the distributed system domain requirements, it still n...

The random time delay in a networked control system can usually deteriorate the control performance and stability of the networked control system. In order to solve this problem, this paper puts forward a networked control system random time-delay compensation method based on time-delay prediction and improved implicit generalized predictive control (GPC). The least squares support vector machi...

The applicability of Model Based Networked Control Systems (MB-NCS) is often limited by the inexact knowledge of the dynamics of the system being controlled. On-line identification of system parameters is used in this paper to upgrade the model of the system, which is used to control the real system when feedback information is unavailable. Background material is offered on the topic of paramet...
