Adaptive vibration control of hoop truss structure using voice coil actuator

Abstract

The vibration of hoop truss structure can be attenuated effectively through the voice coil actuator (VCA) under an adaptive LMS-based feedback strategy. The governing equations of the hoop truss with voice coil actuator are obtained using finite element method. The LMS-based feedback control theory is introduced and a simulation on adaptive vibration control of hoop truss structure with voice coil is done under the LMS-based feedback control strategy. The results of the simulation indicate that adaptive LMS-based feedback control using VCA is a viable control mean.
