摘要
针对航天测控系统由人工进行决策判断带来的滞后性,提出一种航天测控系统联调实时决策方法。将测控系统按照层次进行建模,根据联调中测控设备发送的信息,通过适当的量化模型转化为可信度值,使用基于可信度的不确定性推理理论,将一系列推理规则转化为代数运算,计算得到测控设备的工作状态,并采用同样的方法,按照层次模型自底向上对整个系统进行实时决策,计算得到整个测控系统工作状态。实验表明该方法能有效、快速决策航天测控系统的工作状态。
Against the lag for manual decision of aerospace TTC system,this paper proposed a real-time decision method for aerospace TTC system.This method first models the TTC system by system-level and transforms into credibility value based on the information from TTC equipment and the proper quantitative model.By using uncertainty reasoning theory based on the reliability,it transforms a series of reasoning rules into algebra operations,calculating the working state of the TTC equipment,and by using the same method,according to level model from the bottom up to top to the whole TTC system of real-time decision,it calculates the whole system working state.The results show that the method can effectively and rapidly decide aerospace TTC system working state.
