Smart matter consists of many sensors, computers and actuators embedded within materials. These microelectromechanical systems allow properties of the materials to be adjusted under program control. In this context, we study the behavior of several organizations for distributed control of unstable physical systems and show how a hierarchical organization is a reasonable compromise between rapid...
As we move towards an era of Smart Environments, mixed technological and social solutions must be examined to continue to allow users some control over their environment. Realisations of Smart Environments such as Smart Cities and Smart Buildings bring the promise of an intelligently managed space that maximises the requirements of the user while minimising resources. Our approach is to create ...
As the vision of ubiquitous computing becomes reality smart devices are embedded into our surroundings and domestic appliances providing services transparently. The nature of such smart computing environments is open and dynamic; therefore the use of predefined security associations between all of the participating devices is particularly difficult. Our proposal, called ÆTHER, defines a securit...
Chatter is an instability phenomenon in machining processes which limits productivity and results in inferior workpiece quality, noise and rapid tool wear. The increasing demand for productivity in the manufacturing community motivates the development of an active control strategy to shape the chatter stability boundary of manufacturing processes. In this work a control methodology for the high...
In this Keynote Lecture, first a novel wavelet-hybrid feedback least mean square (LMS) algorithm is presented for robust control of civil structures through adroit integration of a feedback control algorithm such as the LQR or LQG algorithm, the filtered-x LMS algorithm, and wavelets. Next, a new hybrid control system is presented through judicious integration of a passive supplementary damping...
This paper deals with hierarchical model predictive control (MPC) of smart grid systems. The design consists of a high level MPC controller, a second level of so-called aggregators, which reduces the computational and communication-related load on the high-level control, and a lower level of autonomous consumers. The control system is tasked with balancing electric power production and consumpt...
With the advent of the smart energy grid – an energy transportation and distribution network being combined with an IT network for its monitoring and control – information security has gained tremendous importance for energy distribution and energy automation systems. Integrated security functionality is crucial to ensure a reliable and continuous operation of the smart energy grid. Further sec...
Data collected by Automated Fare Collection (AFC) systems are a valuable resource for studying the travel habits of large city inhabitants. In this paper, we present an approach to mining the temporal behavior of the passengers in a public transportation system in order to extract relevant and easily interpretable clusters. Such classification can be useful for several applications. It may help...
This paper presents the application of smart control technology to reinforced concrete systems for high impact force attenuation. The smart reinforced control system is developed through the integration of reinforced concrete beams, smart control devices, sensors, and signal processors. Various combinations of input and output signals are applied to the smart reinforced concrete beams: impact f...
The optimal integration of electrical units, such as distributed generation power electronic devices, and electric vehicles, is a significant development smart grids. This has effectively transformed the traditional grid system, promising numerous advantages for economic values autonomous energy source control. In grids development, metaheuristic algorithms are one optimization that have been a...
