Abstract

Dynamic modeling of smart hull structure with advanced piezoelectric actuator; macro-fiber composite (MFC) actuator, is developed and control performance to suppress structural vibration of the system is studied. Finite element technique is used to ensure application to practical geometry and boundary conditions of smart hull structure. Modal analysis is conducted to investigate the dynamic characteristics of smart hull structure. For the verification of the proposed finite element model, numerical results of modal analysis are compared with those of experimental modal test results. Modal mass and stiffness matrix of smart hull structure are extracted for the controller design. Active controller is designed to suppress structural vibration of smart hull structure and control performance is evaluated in the resonance and non-resonance regions.
