【摘要】 提出并实现了基于实时预测轨迹修正的单检测型复合轴控制方法。利用一个目标探测与处理系统即可同时实现粗、精跟踪闭环。在目标提取困难时可有效提高跟踪可靠性,降低了光电跟踪设备对探测器的探测能力的苛刻要求及高度依赖性,同时,降低了粗精跟踪控制器带宽匹配的要求。本文在对比一般单检测型复合轴控制方法的基础上给出了实时轨迹修正单检测型复合轴控制方法的原理,速度修正所使用的预测滤波方法,以及跟踪实验结果。实验结果表明了该方法的有效性和可靠性。更多还原

【Abstract】 A new tracking algorism for single detector compound axis was presented and realized based on realtime trajectory correcting. Only one target detector system was needed for two-axis close loop control, which improved tracking reliability and degraded the requirements for the detective ability of CCD system. Precise results could be obtained even though CCD system hardly detected target in short time. The principle of realtime trajectory correcting single detector compound axis control in photoelectric tracking system was introduced through comparison between this method and common single detector compound axis control track method. The Experiment result verifies the effectivity and reliability of the method.更多还原
