Zusammenfassung:The invention discloses a gust response retarding method of a wing based on a variable-camber flexible trailing edge, and relates to the field of gust mitigation control of flexible aircrafts. The method comprises the steps of firstly, designing a flexible trailing edge structure based on a corrugated plate form for a certain type of wing; then, establishing a wing finite element model to obtain corresponding modal information; thirdly, identifying training data obtained through CFD by an observer method, and creating a wing trailing edge deflection generalized unsteady aerodynamic force reduced-order model; utilizing a surface element method to calculate modal and gust aerodynamic force; establishing a wing open-loop gust response model by the aerodynamic model and the modal information; and finally, adopting a flexible trailing edge as a control surface, taking the wingtip acceleration as a feedback input signal, calculating and designing a closed-loop control law by a GPC method, and adding a closed loop b
