Adaptive feedforward broadband vibration (or noise) compensation is currently used when a correlated measurement with the disturbance is available. Most of the active vibration control systems feature an internal " positive " mechanical feedback between the compensation system and the reference source (a correlated measurement with the disturbance). Such systems have often also a feedback control loop for reducing the effect of disturbances. For stability reasons the adaptation algorithms require the implementation of a filter on observed data or a filtering of the residual acceleration in order to satisfy some passivity conditions. Recently the use of the " Integral + Proportional " (IP) adaptation has been proposed. The paper provides a general algorithms for the adaptive feed-forward compensation which includes as particular cases the various algorithms presented in the literature. The algorithm has been applied to an active vibration control system.
