Optimal multirate control of the networked control systems is investigated in this paper. Under p – to – wσ communication sequence that sensors access communication medium and m – to – wρ communication sequence that actuators access communication medium, the plant of networked control system acts as a linear periodic time-varying system. Using lifting technology, a linear periodic time-varying ...

Security issues are becoming more and more important to activities of individuals, organizations and the society in our modern networked computerized world. In this chapter we survey a few optimization frameworks for problems related to security of various networked system such as the internet or the power grid system.

We attempted to design and assess an example of a sustainable networked delivery (SND) system: a hybrid business-to-consumer book delivery system. This system is intended to reduce costs, achieve significant reductions in energy consumption, and reduce environmental emissions of critical local pollutants and greenhouse gases. The energy consumption and concomitant emissions of this delivery sys...

triple helix model (th) collaborations involving university, industry and government provide a networked infrastructure for shaping the dynamic fluxes of knowledge base of innovations locally and these fluxes remain emergent within the domains. in this article first the knowledge-based economy, national system of innovation, and three models of uig relations which represent different triple hel...

The integration of physical systems through computing and networking has become pervasive, a trend now known as Cyber Physical Systems (CPS). Functionality in CPS emerges from the interaction of networked computational and physical objects. System design and integration are particularly challenging because fundamentally different physical and computational design concerns intersect. The impact ...

In the recent years the usage of data networks has been increased due to its cost effective and flexible applications. A shared data network can effectively reduce complicated wiring connections, installation and maintenance for connecting a complex control system with various sensors, actuators, and controllers as a networked control system. For the time-sensitive application with networked co...

Existing wireless network architectures are often poorly suited to the growing diversity of up-coming networked robot systems. As networked robots depend on reliable wireless communication to operate effectively as a team of networked robots, it is important that the communication system is scalable. One of the existing challenges in wireless communication is maintaining the bandwidth throughpu...

Highly dynamic and heterogeneous distributed systems are challenging today’s middleware technologies. Existing middleware paradigms are unable to deliver on their most central promise, which is offering interoperability. In this paper, we argue for the need to dynamically synthesise distributed system infrastructures according to the current operating environment, thereby generating “Emergent M...

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...

Networked Controlled systems (NCSs) are composed of actuators, sensors and controllers distributed over the network. A NCS is a control system in which the regulation loops are closed by the communication network (Zhang et al., 2001). However, it is necessary to ensure the stability of the process control, taking into account the performances of the network (Branicky et al., 2003). NCSs are mor...
