摘　　要：针对多柔性梁耦合系统的振动特性以及主动控制问题,设计并建立了实验平台。为了得到准确的模型,提出了一种基于小波变换和灰狼寻优算法的实验辨识方法,对有限元模型进行修正。为实现振动快速抑制,设计了基于最小参数学习法的径向基网络反步滑模控制(radial basis function network backstepping slide mode control,简称RBF-BSSMC)算法。实验结果表明,相比于比例微分(proportional-derivative,简称PD)控制,RBF-BSSMC算法可以实现快速振动抑制,特别是小幅值振动。Aiming at the vibration characteristics and active control of a multi-flexible beam coupling system,an experimental platform is designed and built.In order to obtain accurate model,an experimental identification method based on wavelet transform and grey wolf optimization algorithm is proposed to modify the finite ele⁃ment model.In order to suppress vibration quickly,a radial basis function network backstepping slide mode con⁃trol(RBF-BSSMC)algorithm based on minimum parameter learning method is designed.The experimental re⁃sults show that,compared with proportional-derivative(PD)control,the RBF-BSSMC algorithm can achieve rapid vibration suppression,especially small amplitude vibration.
