摘      要：Gust alleviation is very important to a large flexible aircraft.A nonlinear low-order aerodynamic state space model is required to model the nonlinear aeroelastic responses due to *** on the proper orthogonal decomposition method,a reduced order modeling of gust loads was *** then the open-loop and closed-loop reduced order state space model for the transonic aeroelastic system was *** static output feed back control scheme was used to design a simple multiple-in multiple-out(MIMO)gust alleviation control *** control law was demonstrated with the Goland+wing model with four control *** simulation results of different discrete gusts show the capability and good performance of the designed MIMO controller in transonic gust alleviation.
