Download or read book Signal Processing for Active Control written by Stephen Elliott and published by Elsevier. This book was released on 2000-09-26 with total page 531 pages. Available in PDF, EPUB and Kindle. Book excerpt: Signal Processing for Active Control sets out the signal processing and automatic control techniques that are used in the analysis and implementation of active systems for the control of sound and vibration. After reviewing the performance limitations introduced by physical aspects of active control, Stephen Elliott presents the calculation of the optimal performance and the implementation of adaptive real time controllers for a wide variety of active control systems.Active sound and vibration control are technologically important problems with many applications. 'Active control' means controlling disturbance by superimposing a second disturbance on the original source of disturbance. Put simply, initial noise + other specially-generated noise or vibration = silence [or controlled noise]. This book presents a unified approach to techniques that are used in the analysis and implementation of different control systems. It includes practical examples at the end of each chapter to illustrate the use of various approaches.This book is intended for researchers, engineers, and students in the field of acoustics, active control, signal processing, and electrical engineering.

This book was released on 2020-09-30 with total page 390 pages. Available in PDF, EPUB and Kindle. Book excerpt: 14th International Conference on Turbochargers and Turbocharging addresses current and novel turbocharging system choices and components with a renewed emphasis to address the challenges posed by emission regulations and market trends. The contributions focus on the development of air management solutions and waste heat recovery ideas to support thermal propulsion systems leading to high thermal efficiency and low exhaust emissions. These can be in the form of internal combustion engines or other propulsion technologies (eg. Fuel cell) in both direct drive and hybridised configuration. 14th International Conference on Turbochargers and Turbocharging also provides a particular focus on turbochargers, superchargers, waste heat recovery turbines and related air managements components in both electrical and mechanical forms.

Download or read book Sensor Modelling Design and Data Processing for Autonomous Navigation written by Martin David Adams and published by World Scientific. This book was released on 1999 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This invaluable book presents an unbiased framework for modelling and using sensors to aid mobile robot navigation. It addresses the problem of accurate and reliable sensing in confined environments and makes a detailed analysis of the design and construction of a low cost optical range finder. This is followed by a quantitative model for determining the sources and propagation of noise within the sensor. The physics behind the causes of erroneous data is also used to derive a model for detecting and labelling such data as false. In addition, the author's data-processing algorithms are applied to the problem of environmental feature extraction. This forms the basis of a solution to the problem of mobile robot localisation. The book develops a relationship between the kinematics of a mobile robot during the execution of successive manoeuvres, and the sensed features. Results which update a mobile vehicle's position using features from 2D and 3D scans are presented.

Download or read book Adaptive Predictive Signal Processing for Integrated Sensors written by Simon Hainz and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2009-08 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Precise speed and angle measurements of rotating shafts are very important in automotive engineering applications. Due to their high degree of robustness and low production costs, magnetic field sensors are the preferred types of sensors for such applications. The main disadvantage of using the magnetic technique is its limited angle accuracy, which is caused by a systematic error of the sensing arrangement. High integration densities of new semiconductor technologies allow the integration of complex digital signal processing onto a small silicon area. Due to new technologies, high processing power is also available on the small chip area of integrated sensors. This thesis presents a solution for increasing the angle accuracy of a magnetic sensing arrangement by using the processing power available on today's integrated sensors. A digital filter with adaptive and predictive algorithms estimates and compensates for systematic errors by using a simplified physical model of the arrangement. The physical parameter values of the arrangement are known after adaption is completed. With the proposed filter structure the accuracy of the sensing arrangement can be defined by chip design.

This book was released on 2012 with total page 219 pages. Available in PDF, EPUB and Kindle. Book excerpt: Affordable, wearable, embedded, wireless medical sensor systems that enable continuous long term monitoring of physiological signals could revolutionize health care. Realizing this vision demands devices that are small, unobtrusive and low power. Effectively inferring health conditions begins by acquiring physiological signals of interest and decisions made about what signals are acquired, when, where and at what rate affect not only the energy efficiency of the sampling process but also that of other downstream components in the signal processing chain. While the Nyquist sampling theorem provides for exact reconstruction from discrete-time samples, the prescribed rate is often wasteful for physiological sensing applications since it neither exploits the structure of signals fully nor does it take into account that many applications don't require full reconstruction at all. This dissertation illustrates how energy efficiency of the entire system can be improved by targeting just the signal acquisition process while being cognizant of the entire sensing information stack, from sampling, processing and communication to the top-level application inferences. A key ingredient that makes optimizing the sensing stack worthwhile is that the sampling stage, which is usually abstracted away from the system, can now utilize sophisticated methods that have emerged in the past few years. Recent advances in sampling and recovery techniques have demonstrated considerable rate reductions by employing stronger models of the phenomenon coupled with application-specific objectives (detection or control vs. reconstruction), which potentially translates to higher energy, processing and communications efficiency at the system level. This research describes four major thrusts that span the processing chain from hardware to algorithms to inferences. First, recognizing that signal conditioning front-end circuits could account for a large portion of the energy expenditure in low power sensing, we demonstrate how prudently duty cycling them could increase device lifetime by threefold and reduce data rate by almost fourfold for an electrocardiography monitor. Then, we go on to show how one could further slash data rates using the new theory of compressed sensing. For a neural spike recorder, we exploit the fact that action potentials have both a structure and short term stability in their morphology. This meant that we could utilize historical signal information to optimize and adapt compressed sensing recovery, with only receiver-side modifications, doubling the compression ratio. Third, since body area networks are prone to congestion and interference, we propose a rate control algorithm for the wireless channel so that the most important data from the most informative sensors gets delivered for maximum inference quality. Finally, we prove that compressedsensing could be utilized not only to compress signals but could also improve the robustness of sensor transmissions at low computational cost by viewing it as joint source-channel coding for wireless erasure channels.
