摘　　要：针对如何进行姿态敏感器配置的问题,提出了一种确定最优姿态敏感器配置的方法.首先,将工程中的姿态敏感器配置问题用数学模型进行描述;其次,以可靠性为基础,建立系统可靠性模型;然后,引入等价因子这一概念,将配置可选方案之间的优劣以可靠性的形式等价到控制系统中,将系统可靠性模型转化为系统等价可靠性模型;最后,通过对比系统等价可靠性模型的具体数值,确定出最优的航天器姿态敏感器配置方案.文章最后,以一工程实际为例,利用该方法进行姿态敏感器配置的确定,结果表明该方法可行和有效,对工程具有理论指导意义.Considering how to configure the attitude sensor,a method of determining the optimal attitude sensor configuration is proposed.Firstly,the problem of attitude sensor configuration in engineering is described by mathematical model.Secondly,based on reliability,a system reliability model is established.Thirdly,the concept of equivalence factor is introduced,and the advantages and disadvantages of the alternatives are equivalent to the system in the form of reliability.The system reliability model is transformed into the system equivalent reliability model.Fourthly,the optimal spacecraft sensor configuration can be determined by the calculated value of the system equivalent reliability model.At last,the engineering practice is taken as an example.This method is used to configure the spacecraft attitude sensor.The results show that this method is feasible and effective,and has theoretical guiding significance for engineering.
