Adaptive active control of noise and vibration

The design implementation of an active control mechanism for noise cancellation vibration suppression within an adaptive control framework is presented. A control mechanism is designed within a feedforward control structure on the basis of optimum cancellation at an observation point. The design relations are formulated such that to allow on-line design and implementation and thus result in a self-tuning control algorithm. The algorithm is implemented on an integrated digital signal processing and transputer system and results verifying the performance of the algorithm are presented and discussed.
