简要介绍了导航系统的两种χ2检验算法,分析给出了模型误差对两种故障检测算法影响的表达式,指出了在利用χ2检验算法进行故障检验时应注意的问题,最后利用模拟数据和实测数据分别计算比较了模型误差对两种χ2检验算法的影响。
Two kinds of χ2 test algorithms of navigation system are briefly introduced. The expressions of the influence of model errors on the two fault detection algorithms are given. The problems that should be paid attention to when using the χ2 test algorithm for fault detection are pointed out. Finally, by using the simulation data and The measured data were calculated and compared the impact of model error on two kinds of χ2 test algorithm.
