Abstract:

This paper presents a new method for active damping control of intelligent truss structures using a piezoelectric active member by a local integral force and velocity feedback. The feedback control law has good stability and robustness, in which the active member is controlled with the compounded integral force and velocity feedback on the voltage applied to it. Control experiments are conducted on a space truss structure to show that the presented method is very effective in damping vibration response of the structure.
