摘要
针对组合导航系统的故障检测问题,提出了一种基于自适应加权和卡尔曼滤波相结合的自适应滤波新方法。它不仅可以检测出系统故障,而且可以对故障大小进行跟踪估计,同时可以对故障进行具体定位。仿真表明,该方法能够快速有效地对组合导航系统的故障进行检测和隔离,计算速度快,实时性好,可以很好地保证组合导航系统的安全可靠性。
Contraposed the failure test of intergraded navigation system,a new approach based adaptive filter is proposed in this paper.It is a way that not only can detect the failure but also estimate the failure value,and at the same time locate the fault.The simulation results show that this method can detect and isolate the failed component primely.The security and reliability of navigation system can be assured very well.
