β¦ Synopsis
This paper presents the design and implementation of an active control mechanism for noise cancellation and vibration suppression within an adaptive control framework. 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 (DSP) and transputer system. Simulation results verifying the performance of the algorithm are presented and discussed.

Three feedforward active noise control algorithms based on H2, Ha, and modified H2 optimal model matching principles are investigated in this study. The first two methods provide significant attenuation for broadband random noises. However, the H2 and Ha methods generally result in high-gain control
