摘要：
This paper addresses a general case of an active noise control problem with bandlimited random excitations. In order to realize the benefits of both feedback and feedforward control strategies, this study has concentrated on a combined adaptive feedforward/feedback (hybrid) active noise control architecture. Feedforward control is to attenuate the noise with frequency contents correlated to a reference signal, provided by the sensory output, and feedback is to attenuate the residual noise. Theoretical analysis of this hybrid control, and the required software and hardware designs for implementation of the proposed system are presented. The resulting controller has been applied to a common noise control problem, i.e. acoustic radiation. Experimental results from the implementation of this controller are discussed.
