Download or read book Adaptive and Robust Active Vibration Control written by Ioan Doré Landau and published by Springer. This book was released on 2016-09-15 with total page 405 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book approaches the design of active vibration control systems from the perspective of today’s ideas of computer control. It formulates the various design problems encountered in the active management of vibration as control problems and searches for the most appropriate tools to solve them. The experimental validation of the solutions proposed on relevant tests benches is also addressed. To promote the widespread acceptance of these techniques, the presentation eliminates unnecessary theoretical developments (which can be found elsewhere) and focuses on algorithms and their use. The solutions proposed cannot be fully understood and creatively exploited without a clear understanding of the basic concepts and methods, so these are considered in depth. The focus is on enhancing motivations, algorithm presentation and experimental evaluation. MATLAB®routines, Simulink® diagrams and bench-test data are available for download and encourage easy assimilation of the experimental and exemplary material. Three major problems are addressed in the book: active damping to improve the performance of passive absorbers; adaptive feedback attenuation of single and multiple tonal vibrations; and feedforward and feedback attenuation of broad band vibrations. Adaptive and Robust Active Vibration Control will interest practising engineers and help them to acquire new concepts and techniques with good practical validation. It can be used as the basis for a course for graduate students in mechanical, mechatronics, industrial electronics, aerospace and naval engineering. Readers working in active noise control will also discover techniques with a high degree of cross-over potential for use in their field.

Available in PDF, EPUB and Kindle. Book excerpt: This book presents the design, analysis, and application of nonlinear adaptive filters with the goal of improving efficient performance (ie the convergence speed, steady-state error, and computational complexity). The authors present a nonlinear adaptive filter, which is an important part of nonlinear system and digital signal processing and can be applied to diverse fields such as communications, control power system, radar sonar, etc. The authors also present an efficient nonlinear filter model and robust adaptive filtering algorithm based on the local cost function of optimal criterion to overcome non-Gaussian noise interference. The authors show how these achievements provide new theories and methods for robust adaptive filtering of nonlinear and non-Gaussian systems. The book is written for the scientist and engineer who are not necessarily an expert in the specific nonlinear filtering field but who want to learn about the current research and application. The book is also written to accompany a graduate/PhD course in the area of nonlinear system and adaptive signal processing.

Available in PDF, EPUB and Kindle. Book excerpt: The objective of this project was to develop and analyze advanced adaptive schemes for the active attenuation of sound and vibration. Implementations of algorithms such as the filtered-X LMS algorithm were proposed that require fewer computations than the standard implementation. Delay compensation techniques were also developed to combat performance reducing effects due to delay within the parameter updates. In particular, the extension of the method to adaptive echo cancellation was investigated. Progress was also made on adaptive algorithms for the rejection of periodic disturbances without measurement of the disturbance or of its frequency. A direct approach and an indirect approach were studied, and the resulting algorithms were tested successfully on an active noise control testbed. Disturbances with multiple harmonics and multi-channel systems were both considered.

Download or read book Active Control of Impact Acoustic Noise written by Guohua Sun and published by . This book was released on 2013 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: Active noise control (ANC) has drawn widespread research interest in both academia and industry during the last two decades, especially in the automotive industry where better vehicle noise, vibration and harshness (NVH) performance is one of the important concerns for vehicle manufacturers. However, most of the current state-of-the-art ANC systems are mainly focused on stationary noises by following Gaussian distribution, and there is limited research work on ANC of impulsive and/or impact noise. In practice, there are many unwanted impact responses at industrial sites and in motor vehicles, such as noise generated by punching machines, combustion engines and pile drivers as well as impact road noise due to road bumps. This type of noise may pose a difficult challenge for the prevalent adaptive control algorithms, namely the filtered-x least mean square (FXLMS) algorithm. Hence, more in-depth understanding is required to design an ANC system with robust and efficient adaptive algorithms for treating impact acoustic noise. The first part of the dissertation concentrates on the development of more robust adaptive algorithms for generic impulsive noise. First, an enhanced modified filtered-x least mean M-estimate algorithm (MFXLMM) is proposed to tackle the impulsive-type noise, where the reference signal is fed through the Hampel's three-part M-estimator by setting thresholds for impulses. Second, a family of enhanced M-estimator based algorithms is proposed, where different types of robust criteria based on robust statistic theory are applied for non-Gaussian impulsive noise. This family of algorithms generalizes all the existing studies by previous researchers. Third, more specific observations are made for the convergence performance of the modified FXLMS algorithm for impact noise, where thresholds in the reference and error signal paths are added. This analysis is to address the underlying mechanism of the enhanced algorithm for impact noise due to the white noise and impulses with different durations. The second part of the dissertation is on impact noise with certain repetitiveness. First, a specific analytical convergence analysis of the FXLMS algorithm for repetitive impulse-induced noise is developed, where pure delay secondary path models are assumed. A step size bound is obtained which is in agreement with the previous studies. Moreover, a general secondary model is considered in the numerical simulations to further demonstrate the feasibility of applying the FXLMS algorithm for repetitive impact noise. Second, comparative experimental and simulation work are conducted to further validate the performance of FXLMS algorithm for repetitive impact noise. The feedback system with the iterative learning control (ILC) algorithm is also designed to compare with the FXLMS algorithm. Finally, a concluding work is performed to apply the enhanced FXLMS algorithm to impact road noise control. A frequency response function (FRF)-based sub-structuring technique is implemented to develop a coupled vehicle system model, where the passenger compartment is simplified as a 3-dimensional flexible-panel backed cavity model and the tire-wheel system is modeled as a flexible ring element and rigid wheel. Numerical simulations are conducted to validate the effectiveness of the proposed ANC system for interior impact road noise.

Download or read book Adaptive Filtering Applications written by Lino Garcia Morales and published by BoD – Books on Demand. This book was released on 2011-07-05 with total page 414 pages. Available in PDF, EPUB and Kindle. Book excerpt: Adaptive filtering is useful in any application where the signals or the modeled system vary over time. The configuration of the system and, in particular, the position where the adaptive processor is placed generate different areas or application fields such as: prediction, system identification and modeling, equalization, cancellation of interference, etc. which are very important in many disciplines such as control systems, communications, signal processing, acoustics, voice, sound and image, etc. The book consists of noise and echo cancellation, medical applications, communications systems and others hardly joined by their heterogeneity. Each application is a case study with rigor that shows weakness/strength of the method used, assesses its suitability and suggests new forms and areas of use. The problems are becoming increasingly complex and applications must be adapted to solve them. The adaptive filters have proven to be useful in these environments of multiple input/output, variant-time behaviors, and long and complex transfer functions effectively, but fundamentally they still have to evolve. This book is a demonstration of this and a small illustration of everything that is to come.
