| 摘 要： | 在原有的噪声被动控制技术的基础上,人们又发展噪声主动控制技术.它能有效的降低低频噪声,但是对于高频控制效果不理想.为此针对高频的实时性和不可控性进行分析,设计了一套采用电流跟踪和桥式放大电路技术的有源滤波的输出电路.并基于Matlab对系统进行了详细的仿真分析.证明了系统是可以实现的.

| Abstract: | On the basis of passive noise control technology,the active noise control technology is developed which can effectively attenuate the low-frequency noise,but it is not ideal for high-frequency noise.On the analysis of the real-time and uncontrollability of high-frequency noise,we designed an active filter output circuit adopting the bridge type amplifier circuit and current-following technologies.At last,we minutely simulated and analyzed this system on Matlab,and proved the system is realizable. |
