Independent Modal Control for Intelligent Space Truss Structures Utilizing an Modal Filter

An active vibration control scheme is discussed which utilizes a modal filter(MF) to estimate modal coordinate states for implementation of modal control for intelligent space truss structures. An experimental example is described through numerical simulations that utilizes active members as the internal actuators of intelligent structure. The results show that the active control scheme for intelligent space structures in this paper is feasible and effective.
