Control of Noise and Structural Vibration presents a MATLAB-based approach to solving the problems of undesirable noise generation and transmission by structures and undesirable vibration within structures, in response to environmental or operational forces. The fundamentals of acoustics, vibration, and coupling between vibrating structures and the sound fields they generate are introduced, including a discussion of the finite element method for vibration analysis. Following this, the treatment of sound and vibration control begins, illustrated by example systems such as beams, plates, and double walls. Sensor and actuator placement is explained as is the idea of modal sensor/actuators. The design of appropriate feedback systems includes consideration of basic stability criteria and robust active structural acoustic control. Positive position feedback (PPF) and multi-mode control are also described in the context of loudspeaker–duct and loudspeaker–microphone models. The design of various components is detailed, including the analog circuit for PPF, adaptive (semi-active) Helmholtz resonators, and shunt piezoelectric circuits for noise and vibration suppression.
The text within the book makes extensive use of MATLAB examples.
