| Abstract: | A theory based-on adaptive control and a method of active noise control (ANC) electronic technology are introduced.The ANC system is developed with a TMS320C25 high-speed digital processor (DSP),and the control algorithm is realized with the assemble and C languages.The experiment on a tractor shows that the maximum SPL(sound pressure level) is decreased approximately 18dB. |
