提出了基于时间最短的无人作战飞机(UCAV)筋斗机动动作实时轨迹生成方法。利用机载计算机预先装订的UCAV气动及三自由度飞机模型,实时生成具有迎角及法向过载保护的最优轨迹指令,同时采用经典控制方法进一步缩小跟踪误差,最终实现了UCAV所需的筋斗机动。仿真结果表明,该方法具有实时性强、生成轨迹易于跟踪控制、可有效保证飞行安全等优点。 A real-time trajectory generation method for the maneuver of the unmanned combat aircraft (UCAV) is proposed based on the shortest time. The pre-bound UCAV aerodynamic and three-DOF aircraft model onboard computer is used to generate the optimal trajectory command with angle of attack and normal overload protection in real time. At the same time, the classical control method is used to further reduce the tracking error and ultimately achieve the required bucket for UCAV Motorized. The simulation results show that the proposed method has the advantages of real-time performance, easy trajectory control and effective flight safety control.
