Active control of connected plates using single and multiple actuators and error sensors

Abstract

Active control of the structure-borne vibration transmission in resonant, built-up structures which typically represent a ship hull is analytically and experimentally investigated. Using feedforward active control, the control performance is compared for both dependent and independent control force arrangements. Multiple actuator control forces and multiple error sensors are used to actively control the frequency response. The global response of the coupled plate structure is also presented for active control at discrete resonance frequencies.
