插头锥套式空中加油对接过程中受油机的飞行控制律

Flight Control of Receiver Aircraft for Probe-Drouge Aerial Refueling Docking

采用基于参考观测器的轨迹跟踪控制方法,实现空中加油过程中受油插头与加油锥套的精确对接.根据受油机插头与加油锥套之间的相对位置,由参考轨迹生成模块实时生成受油机的机动轨迹.通过参考观测器实时估算出受油机期望跟踪的状态量与控制量,再采用全状态反馈控制,使受油机的受油插头与加油锥套对接.仿真结果表明系统具有良好的跟踪控制性能.

A reference observer-based tracking controller is designed to achieve successful docking between the drogue of a tanker aircraft and the probe of a receiver aircraft.A reference trajectory generation module is used to turn the relative position between the drogue and the probe into a smooth reference trajectory. An output tracking observer is designed to estimate the feed-forward control signal and the reference states to be tracked,and a full state feedback controller provides accurate tracking.Simulation results show that integration of observer and controller is effective for achieving accurate aerial refueling docking.
