摘　　要：为了提高双层被动隔振系统隔离低频结构噪声的效果,采用混合隔振思想,将小脑模型神经网络(cerebellar model articulation controller,CMAC)理论与PID控制算法相结合,设计了双层混合隔振系统CMAC与PID复合控制器,仿真分析了双层混合隔振系统在不同低频正弦激励信号下的加速度和加速度功率谱。仿真结果表明,采用CMAC与PID复合控制的双层混合隔振系统的隔振效果要优于被动双层隔振系统的隔振效果。In order to improve the passive two stage vibration isolation effectiveness,the CMAC（cerebellar model articulation controller） neural theory combined with PID control of the two stage hybrid vibration isolation was designed.The acceleration and the power spectral density of acceleration of the two stage hybrid vibration isolation which was excited in different low frequency signals was simulated.Simulation results show that the effectiveness of the method which is compound control of CMAC and PID is better than passive two stage vibration isolation.
