Control of Sound and Vibration
ENG ME 760
Physical principles and multivariable control techniques involved in the active control of sound and vibration. Topics in sound control include reduction of noise in ducts, structural control to reduce acoustic radiation, and sound field control in enclosures. Vibration control for both lumped and distributed parameter systems, with examples from space structure control and active vibration isolation. Control techniques include feedback and feed forward approaches, LMS adaptive algorithms, linear quadratic regulators, and modern robust control techniques. Effects of system modeling errors and simplifications (i.e., modal truncation) are studied. Laboratory experience implementing a vibration-control scheme for a cantilever beam.
