| Abstract: | The characteristics of diesel engine exhaust noise were analyzed.Adaptive feedward active noise control system was utilized to control noise.The model to control intermittent diesel exhaust noise was established and an elementary design was proposed.Based on diesel engine operation state,the high-speed signal processing chip TMS320F2812 was programmed and debugged to accomplish adaptive algorithm.The validity of the proposed method was verified by real data and DSP simulation experiment. |
| Keywords: | adaptive active noise control DSP simulation |
