摘要
针对交会对接任务中地面训练仿真与实际飞行任务的天地一致性问题,研究了仿真中的关键误差并提出了对策.以航天员在回路中的感知为焦点,从仿真模型、视觉感知和操作感知等3个方面进行了误差特性分析研究.通过训练样本数据,讨论了自控/人控模式下训练仿真误差对航天员实飞操作品质的影响,提出了模型构建、过程修正和地面辨识等误差对策.试验结果表明,对策可行,时间延迟和操作精度响应仿真拉偏有效.误差分析和对策方法对训练模拟器研制和航天员训练有重要应用价值.
Important errors existed in the consistency problem of ground training simulation with actual space flight in rendezvous and docking mission are investigated and countermeasures are put forward. Three characteristics of errors generated from simulation models, visual perception and operation perception are studied by focusing on astronauts' perception in the loop. The influence of training simulation errors in both autonomous docking mode and manual docking mode on astronaut's handling quality in real flight is analyzed in detail based on data of training samples, and approaches of model construction, midway-amending and identification are proposed. The statistic of simulation shows that the countermeasures are applicable, and the configurable bias of time delay and handling response in simulation are effective. The analyzing of simulation errors and countermeasures has a good application value for development of training simulator and astronauts; training.
