The present paper describes experimental and analytical results of gust response of a 1/9-scale transport-type wing with a gust load alleviation system. A reduced-order feedback control filter is formed with the aid of a modified optimal control theory. The system using the feedback filter has been confirmed to be effective against both sinusoidal gust and atmospheric turbulence. Detailed comparison is made by taking into account the effect of location of the leading- and the trailing-edge control surfaces. In general, agreement between analysis and experiment is good.
