Description
This book is about signal processing and active control, and it covers a variety of techniques that can be used in order to control sound and vibration. The book is divided into chapters, and each chapter focuses on a specific topic related to active control. Each chapter includes practical examples that help to illustrate the concepts discussed in the chapter. This book is intended for researchers, engineers, and students in the field of acoustics, active control, signal processing, and electrical engineering.
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.
