Abstract

This paper presents an active damping control of an intelligent truss structure using pair of piezoelectric stack actuators collinear with force transducers and a H¥ robust control strategy. A finite element model of the structure is constructed using the three-dimensional frame elements considering electro-mechanical coupling between the host structure and piezoelectric stack actuator.

In this paper, the active member placement is determined by using the fraction of modal strain energy as an optimal index. The performance objectives and robustness to high frequency unmodeled dynamics are considered in the controller design. The purpose of the controller is to minimize the effect of disturbances on the entire structure. The numerical simulation results demonstrate that the active members of the structure and the robust control strategy can effectively reduce truss vibrations.
