This book was released on 2008 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract (Partial): The vibration control problem for flexible structures is examined within the context of overall controller performance and power reduction. First, the issue of optimal sensor and actuator placement is considered along with its associated control robustness aspects. Then the option of alternately activating subsets of the available devices is investigated. Such option is considered in order to better address the effects of spatiotemporally varying disturbances acting on a flexible structure while reducing the overall energy consumption. Towards the solution to the problem of optimal device placement, three different approaches are proposed. First, a computationally efficient scheme for the simultaneous placement of multiple devices is presented. The second approach proposes a strategy for the optimal placement of sensors and collocated sensor/actuator pairs, taking into account the influence of the spatial distribution of disturbances. The third approach provides a solution to the actuator location problem by incorporating considerations with respect to preferred spatial regions within the flexible structure.

Download or read book Data driven Sensor Placement Methods written by Krithika Manohar and published by . This book was released on 2018 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The scalable optimization of sensor placement remains an open challenge in engineering and physical sciences. Optimal placements can only be determined in general using a brute-force combinatorial search over the domain. This explosion in complexity presents a major challenge for high-dimensional domains in oceanography, fluid dynamics, manufacturing, and biology. Fortunately, high-dimensional data generated by these systems often possess reproducible, low-rank structure that can be exploited to drastically reduce the amount of measurements required for global inference. In this thesis, we exploit data-driven learning to optimize sensor placement for signal reconstruction. Dimensionality reduction methods including proper orthogonal decomposition (POD) and dynamic mode decomposition (DMD) are used to obtain low-rank representations from data. We exploit empirical interpolation methods (EIMs), initially pioneered in reduced order modeling, to efficiently optimize the placement of sensors for high-dimensional reconstruction, estimation and control. This work connects our EIM-based method to related placement criteria in optimal experimental design, and extends our method to obtain an arbitrary number of optimal sensors. The superior performance and accuracy of our method is demonstrated on a variety of high-dimensional data from facial images, ocean temperatures, fluid dynamics, aircraft manufacturing and insect flight. Finally, an extension to sensor and actuator placement for optimal closed-loop control is proposed, which similarly leverages balanced model reduction of observability and controllability Gramians for speedy sensor and actuator optimization.

Download or read book Smart Civil Structures written by You-Lin Xu and published by CRC Press. This book was released on 2017-04-11 with total page 548 pages. Available in PDF, EPUB and Kindle. Book excerpt: A smart civil structure integrates smart materials, sensors, actuators, signal processors, communication networks, power sources, diagonal strategies, control strategies, repair strategies, and life-cycle management strategies. It should function optimally and safely in its environment and maintain structural integrity during strong winds, severe earthquakes, and other extreme events. This book extends from the fundamentals to the state-of-the-art. It covers the elements of smart civil structures, their integration, and their functions. The elements consist of smart materials, sensors, control devices, signal processors, and communication networks. Integration refers to multi-scale modelling and model updating, multi-type sensor placement, control theory, and collective placement of control devices and sensors. And the functions include structural health monitoring, structural vibration control, structural self-repairing, and structural energy harvesting, with emphasis on their synthesis to form truly smart civil structures. It suits civil engineering students, professionals, and researchers with its blend of principles and practice.

Download or read book Distributed Large Scale Dimensional Metrology written by Fiorenzo Franceschini and published by Springer Science & Business Media. This book was released on 2011-06-06 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of large-scale dimensional metrology (LSM) deals with objects that have linear dimensions ranging from tens to hundreds of meters. It has recently attracted a great deal of interest in many areas of production, including the automotive, railway, and shipbuilding sectors. Distributed Large-Scale Dimensional Metrology introduces a new paradigm in this field that reverses the classical metrological approach: measuring systems that are portable and can be easily moved around the location of the measured object, which is preferable to moving the object itself. Distributed Large-Scale Dimensional Metrology combines the concepts of distributed systems and large scale metrology at the application level. It focuses on the latest insights and challenges of this new generation of systems from the perspective of the designers and developers. The main topics are: coverage of measuring area, sensors calibration, on-line diagnostics, probe management, and analysis of metrological performance. The general descriptions of each topic are further enriched by specific examples concerning the use of commercially available systems or the development of new prototypes. This will be particularly useful for professional practitioners such as quality engineers, manufacturing and development engineers, and procurement specialists, but Distributed Large-Scale Dimensional Metrology also has a wealth of information for interested academics.
