Hardware-In-Loop Simulation of Active Noise Control in Car Cabins

A system of active noise control (ANC) in car cabins was established according to the ANC theory. In the xPC environment of MATLAB/RTW, a hardware-in-loop simulation platform was designed including the ANC controller model, software and hardware. Based on the platform, the optimal position of secondary sound source was decided and then a simulation was made on an actual car. The ANC effect was analyzed in both time-domain and frequency-domain, and the tracking performance of ANC system was also analyzed. The analysis result shows the established system of ANC is effect to reduce the low-frequency noise in car cabins.
