Aerial recovery,dense flight and aerial refueling of unmanned aerial vehicles(UAVs)all involve flight stability and position control of the vehicle in a close-range interference flow field. In view of the background of UAV lateral recovery and release,adopting interference aerodynamic derivative model,the longitudinal small disturbance equation of motion of the vehicle in the close interference flow field is established,and the method using the rudder deflection to simulate the restoring force to achieve the longitudinal positional stability of the UAV is proposed. By using typical vehicle data,adopting the state space analysis method,the cost function is established,the optimal control design of pitch rudder deflection and variable thrust are completed,and the method of achieving the UAV longitudinal close-range-flight stability control is simulated and verified. The feasibility of close-range-flight stability is preliminarily verified.
