【摘要】：平台式惯性导航系统是现代导航的重要设备,由于其所处环境和制造工艺各不相同,导致各个体之间的可靠性有着明显的差异。如果对收集到的性能误差数据进行统一处理,无法准确地反映个体之间的差异性,不利于掌握平台式惯性导航系统个体的可靠性规律。针对该问题,对平台式惯性导航系统的在线可靠性评估方法进行了重点研究。结合平台式惯性导航系统使用过程中的性能变化特点和失效机理,利用复合Poisson过程建立了其性能退化模型,并给出了性能参数评估方法。通过算例分析,说明建立的性能退化模型能够较好地描述平台式惯性导航系统的性能退化规律,有助于掌握平台式惯性导航系统的可靠性水平。
[Abstract]:Platform inertial navigation system is an important equipment of modern navigation, because of its environment and manufacturing process are different. The reliability of each individual has obvious differences. If the collected performance error data are processed uniformly, it can not accurately reflect the differences between individuals. It is unfavorable to master the individual reliability rule of platform inertial navigation system. The online reliability evaluation method of platform inertial navigation system is studied in detail, which combines the characteristics of performance change and failure mechanism of platform inertial navigation system. The performance degradation model is established by using compound Poisson process, and the evaluation method of performance parameters is given. It is shown that the established performance degradation model can describe the performance degradation law of platform inertial navigation system and is helpful to grasp the reliability level of platform inertial navigation system.
