Research Abstract

In order to make quiet environment the active noise control has been studied by means of the superposition of two sound with opposite phase. Furthermore the active vibration control has been studied to deaden noise generated from structures. However it is difficult to actively insulate sound due to spill-over.
In this study, a self-sensing actuator with perfect collocation was developed for the active vibration control and active sound insulation. As the self-sensing actuator, the piezoelectric film (PVDF) was used. A method using the phase discriminator was proposed to separate the sensor signal from the mixed signal of sensor and actuator.
To deaden the sound generated from structures and insulate the sound, the active vibration control of the thin plate and cylindrical shell was studied by means of the self-sensing actuator in conjunction with H* control theory, mu synthesis and sliding mode control theory. The effectiveness of the present method is verified by simulations and experiment.
