Modal-based nonlinear moving horizon estimation (MHE) and model predictive control (MPC) strategies for very flexible aeroelastic systems are presented. They underpinned by an built from a one-dimensional intrinsic (based on strains velocities) description of geometrically beams unsteady vortex lattice aerodynamic model. Construction modal-based reduced-order the system, employing state-space r...

According to the great importance of safety in aerospace industries, identification of dynamic parameters of related equipment by experimental tests in operating conditions has been in focus. Due to the existence of noise sources in these conditions the probability of fault occurrence may increases. This study investigates the effects of noise in the process of modal parameters identification b...

The modal testing has proven to be an effective and non-destructive test method for estimation of the dynamic stiffness and damping constant. The aim of the present paper is to investigate the modal response of stiffened Fiber Metal Laminated (FML) circular cylindrical shells using experimental and numerical techniques. For this purpose, three types of FML-stiffened shells are fabricated by a s...
