An active vibration control system using an inertial actuator for suppression of multiple unknown and/or time-varying vibrations will be presented and a comparison with an alternative indirect adaptive regulation scheme is presented.Abstract:
An active vibration control system using an inertial actuator for suppression of multiple unknown and/or time-varying vibrations will be presented. The objective is to minimize the residual force by applying an appropriate control effort through the inertial actuator. The system does not use any additional transducer for getting in real-time information upon the disturbances. A direct feedback adaptive regulation scheme for the suppression of multiple unknown and/or time-varying vibrations will be used and evaluated in real time. It uses the internal model principle and the Youla-Kucera parametrization. In the Appendix, a comparison with an alternative indirect adaptive regulation scheme is presented.read more

Active control of vibration, 1st edition
TL;DR: Nelson and Elliott as mentioned in this paper summarized the principles underlying active vibration control and its practical applications by combining material from vibrations, mechanics, signal processing, acoustics, and control theory, and the reader will find particularly interesting the two chapters on the active control of sound radiation from structures: active structural acoustic control.

Paper: The internal model principle of control theory
B. A. Francis,W. M. Wonham +1 more
TL;DR: The Internal Model Principle is extended to weakly nonlinear systems subjected to step disturbances and reference signals and is shown that, in the frequency domain, the purpose of the internal model is to supply closed loop transmission zeros which cancel the unstable poles of the disturbance andreference signals.
