Abstract: An acoustic energy dissipating device (100) comprises an acoustic driver (112) coupled to an acoustic medium and an acoustic sensor (110) for detecting a pressure of the acoustic medium near the acoustic driver. An inverting amplifier (115) and a compensator (114) are placed in a feedback system including the acoustic driver and the acoustic sensor. The compensator modifies the open loop phase response of the feedback system. Specifically, the compensator compensates for transduction device dynamics associated with the acoustic driver and the acoustic sensor to increase a gain margin of the feedback system. More specifically, the phase response of the open-loop system is constrained to alternate between +90 degrees and -90 degrees for each alternating complex conjugate pair of poles and zeros for an operational bandwidth of the device.

Abstract: An adaptive algorithm implemented in digital or analog form is used in conjunction with a voltage controlled amplifier to compensate for the feedthrough capacitance of piezoelectric sensoriactuator. The mechanical response of the piezoelectric sensoriactuator is resolved from the electrical response by adaptively altering the gain imposed on the electrical circuit used for compensation. For wideband, stochastic input disturbances, the feedthrough capacitance of the sensoriactuator can be identified on-line, providing a means of implementing direct-rate-feedback control in analog hardware. The device is capable of on-line system health monitoring since a quasi-stable dynamic capacitance is indicative of sustained health of the piezoelectric element.
