Performance Testing and Analysis of Multi-channel Active Control System for Vehicle Interior Noise Using Adaptive Notch Filter 2019-01-1567

It is considered that slow convergence speed and large calculation amount of commonly used adaptive algorithm in the active control system for interior vehicle noise yield noise reduction performance and hardware requirements problems. In this paper, a 4-channel active control of interior vehicle noise based on adaptive notch filter is established, and road test is carried out to test and analyze the performance of the control system. Firstly, the general mathematic model of the multi-channel active control system based on adaptive notch filter is established. Secondly, a hardware-in-the-loop test bench based on multi-channels adaptive notch filter was set up, to measure the noise reduction performance of ANC system under various working conditions. Finally, the typical test conditions are designed to test the system noise reduction performance, and the road test is carried out and result is analyzed.
