摘要

提出了一种鲁棒有源噪声控制器,可以有效地对二次路径中的非线性失真进行线性化,并用于噪声的衰减。在实际应用中,整个主动控制系统是非线性的,非线性的程度降低了噪声的衰减性能,因此需要主动控制系统补偿非线性畸变。通过计算机仿真,该控制器比传统的LMS控制器具有更好的噪声控制能力。

Hybrid Adaptive Noise Canceller Compensating Nonlinear Distortions
A robust active noise controller is proposed to effectively linearize nonlinear distortions in the secondary path and be applied for attenuating the noise. In real applications, the overall active control system is nonlinear and the performance of noise attenuation is decreased by the extent of nonlinearities, so an active control system compensating nonlinear distortions is needed. Through computer simulations, the proposed controller had better capability of controlling the noises than the conventional LMS controller.
