Vibration Control of the Car Roof With Wavelet Adaptive Algorithm

Piezoceram patches as sensors and actuators are used for active vibration control of car roofs with the method of wavelet adaptive control, which is based on wavelet transformation.The principle of wavelet transformation and wavelet adaptive control based on D-LMS algorithm are analyzed.The relevant experiment system is designed, and the experimental platform is set up.The experiment makes effectual vibration active control of the car roof by the method of wavelet adaptive control and achieves good effect.
