摘要
发动机排气噪声有源控制算法有多种,不同的算法因其复杂程度不同实际的控制效果也不一样。为了找到一种更有效的控制算法,用MATLAB建立Simulink仿真模型对LMS算法进行仿真,从仿真效果判断出在误差通道客观存在的情况下LMS算法的局限性并对LMS算法进行了改进,取得了较好的控制效果。
There are various active noise control algorithms for engine exhaust noise simulation.However,their control effects are different due to the different complexities.To find out a more effective control algorithm,a simulink model for simulation of noise control of an engine exhaust is established using MATLAB code,and the simulation is done based on the LMS algorithm.From the simulation,the limitation of the LMS algorithm is evaluated in the case that the error acoustic path exists,and the LMS algorithm is improved for better control effect.
