The invention relates to an on-orbit high-reliability two-dimensional rotating mechanism control method and satellite-borne software, and relates to the technical field of on-orbit two-dimensional rotating mechanism control, and the method mainly comprises the following steps: controlling a two-dimensional rotating mechanism to capture and track the sun according to an on-orbit detection task and a sun angle condition; in the control process of the two-dimensional rotating mechanism, an exception handling mechanism and a flexible mode switching method are provided; a search mode is set, so that a remote sensing instrument can successfully capture the sun as much as possible under the condition that new offset exists between mechanical structures of a two-dimensional rotating mechanism in a satellite launching process and a ground experiment cannot be completely consistent with an on-orbit condition; the above measures ensure that the remote sensing instrument successfully completes the detection task. The timed waiting mechanism of the mode ensures that the control flow of the two-dimensional rotating structure can still be normally executed under the condition that the state returned by the control software is disordered, and ensures that the satellite-borne software does not enter an endless loop, thereby ensuring that the whole on-orbit task is completed.
本发明涉及一种在轨高可靠的二维转动机构控制方法及星载软件,涉及在轨二维转动机构控制技术领域,其中方法主要包括以下步骤:根据在轨探测任务以及太阳角度情况,控制二维转动机构对日捕获、跟踪。二维转动机构控制过程中,具备异常处理机制和灵活的模式切换方法;设置了搜索模式,保证了在卫星发射过程中二维转动机构的机械结构间存在新偏移、地面实验无法与在轨情况完全一致条件下遥感仪器最大可能地实现成功对日捕获;以上措施保证了遥感仪器成功完成探测任务。模式的定时等待机制保证了在控制软件返回的状态混乱条件下二维转动结构控制流程仍能够正常执行,保证了星载软件不会进入死循环从而保证完成整个在轨任务。
