单轴稳定技术在盘旋跟踪地面目标中的应用

针对小型无人机，设计一种安装于机身左侧下方的单轴光电探测系统来修正视场纵向误差，同时配合无人机的航向控制，对目标进行盘旋跟踪。控制系统在设计过程中采用纵向通道和横向通道解耦、方位失谐量修正和俯仰失谐量修正解耦的控制方式。飞行试验表明，该控制方式能够持续稳定的跟踪地面目标，使地面目标的成像点趋向于光心，达到了盘旋跟踪的预期效果。

Application of Single-Axile-Stabilization Technology on Circled Tracking Ground Targets

A single-axile optical detection system installed on the left side of the UAV body is designed to correct vertical error of the view, and meanwhile to track ground targets coordinating with the UAV heading control. The decoupling of longitudinal channel and lateral channel, and the decoupling of orientation detuning correction and pitch detuning correction is uesd in this control system. The flight experimental result shows that, this control system can track ground targets continuously and steadily, and make the imaging point of the ground target tend to optical center, which achieves the expected effect of the circled track.
