| 摘 要： | 飞行过程中飞机姿态角速度变化会对摆扫式航空相机产生干扰,另外相机在拍摄时飞行方向上的景物与感光介质之间存在相对运动。为消除姿态角速度的干扰和前向像移,设计了一种基于F28335的机载相机两轴稳定平台系统。探讨了伺服控制系统的算法选择,介绍了硬件结构和软件流程。通过摇摆台试验证明,该两轴稳定平台动态精度高、运行可靠,满足相机拍摄时序和精度的要求。

| Abstract: | Changs in the attitude angular velocity will interfere with aerial camera in the flight,and there will be relative motion between scene and the photosensitive medium in the direction of flight while shooting,so that the image motion is generated.In order to eliminate the interference of the angular velocity and image motion,the paper designs a airborne two-axis stabilized platform system based on F28335,and probes the selection of the servo control system algorithm,hardware architect ure,software process deeply.The swing platform test shows that this two-axis stabilized platform meets the requirements of camera timing and accuracy with high dynamic precision,reliable operation. |
