Reserch on Control Strategy for Short Landing of UAV
Reserch on short-range landing performance of fixed wing UAV has great practical significance.Based on the landing flap configuration among the three flap configurations of the target UAV,this paper analyzes the defects of the traditional landing control mode based on fixed throttle,and elaborates the mutual restriction relationship between various landing indicators in the near field at low speed and large attitude from the perspective of dynamics,The important conclusion that"airspeed is the leading inducement affecting landing performance"is drawn,and the closed-loop control scheme of throttle speed is proposed from the perspective of dynamics.In the process of control law design,the combination of linear theoretical analysis and semi physical nonlinear simulation is innovatively adopted,with full ingretation of engineering practical experience,which highlights the particularity and effectiveness of throttle speed control,and improves the landing performance unprecedentedly.
