摘要 介绍了用自适应LMS滤波器离线辨识六面体单元柔性结构模型和逆模型的方法。文中论述了自适应滤波理论和自适应逆控制之间的关系 ,讨论了LMS算法 ,并以实验法测得的六面体单元柔性结构随机振动数据为基础对其模型和逆模型进行了辨识 。 A method of adaptive LMS filter is presented in this paper to identify the model and inverse model of the hexahedral unit of flexible truss. LMS algorithm and the relationship between the theory of adaptive inverse control and of adaptive filtering are expounded. We carry out stochastic vibration experiment on the hexahedral unit of flexible truss. Based on the vibration data we identify the model and inverse model of the truss, which lay the foundation of further research on the adaptive inverse control of the flexible truss.
