一种小型自主飞行器的反馈导引策略

A Feedback Guidance Strategy for an Autonomous Mini-air-vehicle

提出了一种操纵小型飞行器(MAV)在无障碍环境下从给定的初始位置以给定的航向到达指定目的地路径点的导引策略。该策略能很好地完成在连续的位置和速度更新条件下以恒定高度和速度的导引以及路径点之间的旋转速率指令的跟踪。并通过计算机仿真,研究了在离散的位置更新和航向更新(从GPS获得)或航向估计(从GPS位置更新中获得)条件下该导引策略的性能。

The paper presents a guidance strategy to steer a Mini-air-vehicle (MAV) from a given initial position and heading to a specified destination way-point in an obstacle free environment. The strategy achieves perfect guidance at constant altitude and speed under continuous position and heading updates, and perfect tracking of turn rate commands inter waypoint distances. Simulations are used to study the performance of the guidance strategy under discrete position updates from GPS combined with either heading updates obtained from the GPS or heading estimates obtained from GPS position updates.
