This study investigates the feasibility of deploying wireless communication and embedded computing for structural control applications. A feedback structural control system involves a network of sensors and control devices. As control devices are becoming smaller, more cost effective and reliable, opportunities are now available to instrument a structure with large number of control devices. Ho...

This paper considers linear time-invariant decentralized singular systems which are either nonregular or, if they are regular, they have impulsive modes. It derives algebraic necessary and sufficient conditions for making a singular system both regular and impulsefree by decentralized output feedback control laws and decentralized proportional-plus-derivative output feedback control laws.

Supervision based on place invariants (SBPI) is an efficient technique for the supervisory control of Petri nets. In this paper we propose extensions of the SBPI to a decentralized control setting. In our setting, a decentralized supervisor consists of local supervisors, each controlling and observing a part of the Petri net. We consider both versions of decentralized control, with communicatio...

This paper deals with the decentralized control of an interconnected system, where each subsystem has models of all other subsystems (subject to uncertainty). A decentralized controller is constructed based on a reference centralized controller. It is shown that when a priori knowledge of each subsystem about the other subsystems’ models is exact, then the decentralized closed-loop system can p...

Wireless structural sensing has attracted much research interest in recent years. With actuation functionality incorporated in the design of the wireless sensing nodes, a wireless feedback structural control system can be constructed. For wireless structural control systems that face challenges in communication range, latency, and reliability, decentralized system architectures can provide prom...

Network control mechanisms in networks can be categorized by the time scales on which an individual control takes effect and they form a layered structure with respect to the time scales. In high-speed networks, the processing speed of each node is high but the propagation delay is the same as in slower networks, because it is constrained by the speed of light. So, the framework of network cont...

Over the past fifty years the size of computer applications, as gauged by any reasonable measure, has increased exponentially. In contrast, our cognitive capabilities for understanding have not changed. This discrepancy has forced us to look for more abstract representations of systems to reduce the number of elements we have to consider simultaneously in order to understand the system behavior...

A cellular automaton is a decentralized computing model providing an excellent platform for performing complex computation with the help of only local information. Researchers, scientists and practitioners from different fields have exploited the CA paradigm of local information, decentralized control and universal computation for modeling different applications. This article provides a survey ...
