| Abstract: | An embeded active noise control system based on the C6000 DSP is developed.Firstly,the theoretical model of the active noise control system is described,the off-line secondary-path modeling and active noise control method are given by employing the FX-LMS and LMS algorithms.Then the hardware system selecting TMS320VC6416 DSP and AIC23B as the kernel of the controller is developed,and the application software is programmed by using the C language.The experiment shows that the system can reduce the single-frequency noise of 108 Hz by 18 Hz,which verifies its validity and stability. |
