The Design of Vehicle Active Noise Control System
Abstract:With the development of society, the topic of noise control has been paid much attention. the noise control is becoming important and urgent. The works in this domain have been widely investigated all over the world. The adaptive algorithms, According to the idea of forward control, the corresponding weights of this algorithm are given.The controller with TMS320F2812 is explored. The hardware and software are completed based on this controller. The experiment setup is constructed with the vehicle model and this controller, which makes preparations for the real-time control experiment.
