The invention discloses an active noise control method for an air supply unit of an air suspension, comprising a damping regulator and an actuator, the damping regulator analyzes a main frequency according to a reference signal related to the primary noise of the air supply unit, and then adjusts the damping to improve the stability of the air supply unit and reduce the noise; the actuator generates secondary noise according to the primary noise and the residual noise of the air supply unit, and the secondary noise is a sound wave signal which is consistent with the noise propagation direction of the air supply unit, has the same amplitude and is opposite to the noise propagation direction of the air supply unit; the method has the advantages that the control method is relatively simple, and the noise reduction effect is good.

    本发明公开了一种用于空气悬架供气单元的主动噪声控制方法,包括阻尼调节器以及执行器,所述阻尼调节器根据供气单元初级噪声相关的参考信号分析出主频率后,调节阻尼大小提高供气单元的平稳性,减少噪声;执行器依据供气单元的初级噪声以及残余噪声生成次级噪声,所述次级噪声是与供气单元噪声传播方向一致、幅值相同、相位相反的声波信号;本发明的优点在于:控制方法相对简单,降噪效果好。
