An active control strategy is proposed to attenuate the undesirable vibrations of dynamic systems. In this approach the dynamic system is treated as a black-box, whose modal characteristics are not included in the control process. Instead, the control of the system is pursued via utilizing optimization techniques to minimize an objective function formulated based on the response of the system at several locations on the vibrating system. The decision variables of the formulated optimization problem are the magnitudes and phase angles of alternative force components to be exerted at proper location of the system. The proposed method is applied to simulated active control of a rotor system whose unbalance response is to be minimized. |
