设计了非线性制导律，使无人机在绕目标作定距顺时针或逆时针旋转的同时完成给定的使命。距离误差动力学用于考虑风干扰的静止目标观测。利用离散卡尔曼滤波器估计风矢量，并通过考虑风向和大小的制导指令来补偿风效应。数值仿真验证了改进后的非线性制导律的性能。
Nonlinear guidance law is designed to make UAV(Unmanned Aerial Vehicle) accomplish the given mission, while rotating clockwise or counter clockwise around the target with constant distance. Distance error dynamics is used for stationary target observation considering wind disturbance. The wind vector is estimated using a discrete Kalman lter, and the wind eect is compensated by generating guidance commands considering the wind direction and magnitude. Numerical simulations are performed to verify the performance of the modied nonlinear guidance law.
