为解决主从机编队飞行问题,以柱面坐标系为参考坐标系,建立长机与僚机之间的相对运动模型。考虑编队飞行系统所受干扰上确界未知,提出无人机编队队形保持的短时记忆控制律。仿真结果表明,控制能够抑制较大干扰,使系统迅速到达期望状态。控制律简单、快速、有效,对编队飞行实现自主飞行有重要意义。
The model of relative motion between leader and wingman was established with the cylindrical coordinate system as the reference coordinate to solve the problems occurred in the formation flight of UAVs.As the disturbation′s up-bound is unknown,the short-time memory control to keep formation is presented.The simulations demonstrate that the control can depress the effects of large disturbances and make the system get the expected states rapidly.The control law is easy,fast and effective,and has great significance for the autonomous flight of the formation flight.
