Abstract

Abstract:

In order to solve the problem of roaring sound inside the vehicle caused by intermittent engine intervention during charging and discharging of diesel-electric hybrid vehicles， in this paper a semi-coupled cluster control strategy with better comprehensive performance is proposed based on the traditional multi-channel active noise control （ANC） system by combining the advantages of the centralized control strategy and decentralized control strategy. Compared with the centralized control strategy， the computational cost of the cluster control strategy is reduced by about 50%， and the noise attenuation performance is comparable to that of the centralized control strategy. Compared with the decentralized control strategy， the stability is obviously better， and the noise reduction effect is outstanding. Based on the MATLAB simulation platform， a variety of cluster control strategies and traditional control strategies in the vehicle are compared and analyzed， and the road test experiments of a range-extended electric vehicle are carried out under its common working conditions. The results show that the cluster control strategy can be well applied to the multi-channel active noise control system in the vehicle， and the average noise reduction amount of the second-， fourth-， and sixth-order range extender noise at the four seat headrest positions can reach 15.9， 10.6 and 5.7 dB（A）， respectively， showing good noise reduction effect and stability. The research results can be applied to the noise control of manned cabins， such as aircraft， submarines and other fields， which has important scientific significance and engineering value.
