Abstract :
An adaptive inverse control method is proposed for space flexible truss structure vibration control. The purpose is to restrain the displacement amplitude or the acceleration amplitude of the structure vibration, to use the artificial neural network to identify the dynamic space flexible truss structure as the control plant, then obtained the inverse model of the plant utilizing the LMS algorithm. The inverse of the nt is used to train the controller employing the RTRL algorithm. Practical results show that the adaptive inverse control method can effectively achieve the vibration control of the space flexible truss structure.
