Abstract：For precise landing of medium-large fixed wingUAVunder diferent loads，thisarticle，byanalyzing the landingdifficultiesofthetargetUAV，innovatesaproposeofacombinationtrajectory methodofexponential trasition and straight linein the shallow glide section.A sinking rate cascade control law basedon the pitch angle closed一lop controlloopis designed，anda descent rate command guidance scheme is projected acording totrajectory.Therobust simulation verifies the safe landing of the full mass configuration as well as the touchdown accuracy within ±50m ，which confirms the effectiveness and feasibility of the designed scheme.
