敏捷卫星控制分系统动中成像姿态机动模式的集成测试方案设计

摘要

动中成像姿态机动模式作为敏捷卫星一种新的工作模式,具有机动过程复杂、姿态实时变化、指标要求更高的特点,原有的集成测试环境和测试方法难以对其进行有效验证,针对这一问题,设计了分系统集成测试方案.该方案对分系统集成测试环境的主控机、动力学模型和数据分析系统进行设计,实现了基于任务的自主测试、目标姿态计算模型和可视化测试功能,对测试方法中的机动模式的典型测试工况和指标测试进行了研究.测试结果表明,该方案可有效验证控制分系统姿态机动功能的正确性和指标符合情况,为开展分系统集成测试提供了思路.%As a new work mode of agile satellite,dynamic-imaging attitude maneuver mode has such characteristics as complicated maneuver,real time change of attitude and higher performance index.It is difficult to validate the maneuver mode in the existing test environment using current test method.An integration test scheme is designed to solve this problem.The design of test environment contains master control unit,dynamic model and data analysis system.The automatic test,target attitude calculation and visualization of test system are realized.Typical test conditions and performance test are included in the research of test method.The results show that the designed scheme can verify the correctness of function and the validity of performance index,which provides ideas for integration test of control system.
