An Integrated Navigation Fault-Tolerance Algorithm Based on One-Class Support Vector Machine

提出了一种基于单类支持向量机(OCSVM)的组合导航容错算法。针对组合导航系统中子系统出现故障会影响整个导航系统精度的问题,采用基于单类支持向量机的方法,对故障进行检测和隔离,并对容错性能进行分析。仿真结果表明:在应用基于单类支持向量机的容错算法后,系统的故障检测模块可以有效地隔离故障数据,降低了多源组合导航系统的位置误差,其可靠性和稳定性也得到了提高。

An integrated navigation fault-tolerance algorithm based on One-Class Support Vector Machine(OCSVM)is proposed.In the integrated navigation system,the failure of a subsystem will affect the accuracy of the whole navigation system.To solve the problem,the method based on OCSVM is adopted to detect and isolate the fault,and the fault-tolerance performance is analyzed.The simulation results show that,after applying the OCSVM based fault-tolerance algorithm,the fault detection module of the system can effectively isolate fault data,thereby reducing the position error of the multi-source integrated navigation system,and its reliability and stability are also improved.
