基于参考观测器的全状态反馈控制方法设计了受油机飞行控制系统,建立了软管式自主空中加油仿真系统,并进行了仿真验证。根据生成的受油机参考跟踪、对接轨迹,通过输出跟踪观测器在线估算前馈控制信号和参考状态量,设计全状态反馈控制器精确跟踪参考状态,解决了受油插头难以近距离跟踪加油锥套并实现精确对接的问题。以某型UCAV为例,设计了基于全状态反馈控制的自主空中加油仿真系统并进行了数字仿真。仿真结果表明,在四种强度阵风干扰下,设计的空中加油仿真系统能实现精确的双机加油设备跟踪与对接,具有良好的动态性能与鲁棒性能。
Based on the full state feedback control method of reference observer, a receiver controlled flight control system was designed and a hose-based autonomous aerial refueling simulation system was established and simulated. According to the generated receiver reference tracking and docking trajectory, the output tracking observer online estimates the feedforward control signal and the reference state quantity. The full state feedback controller is designed to accurately track the reference state, which solves the problem that it is difficult for the oil plug to closely track the refueling cone Set and achieve accurate docking problems. Taking a certain type of UCAV as an example, an autonomous air refueling simulation system based on full state feedback control is designed and simulated. The simulation results show that under the four kinds of intensity gust disturbance, the designed air refueling simulation system can achieve accurate double-machine refueling equipment tracking and docking with good dynamic performance and robust performance.
