| Abstract: | 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. |
