摘要:

针对卫星导航拒止环境中飞行器编队欠测量相对导航难题,提出一种编队成员之间仅测距离或视线角度的协同相对导航方法。首先,以相对位置、航向角差、速度为基础并纳入传感器有色噪声在内,建立了相对运动状态模型。然后,建立了由仅测距或仅测角两种相对测量和飞行器航向、空速测量信息组成的测量模型,在此基础上引入李导数理论对相对导航状态进行了可观测性分析,获得了激励系统状态可观测性的充分条件。接着,以三个飞行器构成编组并建立几何拓扑一致性约束模型,在此基础上设计了基于一致性无味卡尔曼滤波(consensus unscented Kalman filter,CUKF)算法的分布式估计算法。最后,对所提方法进行了Monte Carlo打靶仿真验证,仿真结果表明,飞行器的运动满足可观测性条件时相对导航状态是可观测的,几何拓扑一致性约束的引入确实提升了系统可观测性,三机编队时混合测量方式相比全员仅测距或测角更具优势,相对位置的估计误差不超过5 m/轴(3σ)。

Abstract:

In view of the problem of accurate relative navigation with insufficient measurement between formation aircraft in a satellite navigation-denied environment, a cooperative relative navigation method is proposed in which the formation members only measure distance or line-of-sight angle between each other. First, with the information of relative position, heading angle difference, velocity, the relative motion state model including sensor colored-noise is established. Then, a measurement model consisting of two relative measurements, distance measurement or angle measurement, and the aircraft heading and airspeed measurement information is established, then observability analysis of the main relative states is conducted based on Lie derivative theory, sufficient conditions for the observability of the incentive system state are obtained. A geometric topology consistency constraint model is established for the formation with three aircraft, based on which a consensus unscented Kalman filter (CUKF) algorithm is established, which is a distributed estimation algorithm. Simulation is introduced with the help of the Monte Carlo shooting method. Simulation results show that when the theoretical analysis of observability is satisfied, the relative navigation states can be observed, and the introduction of geometric topological consensus constraints can improve the observability of the system. The hybrid measurement scheme with three aircraft formation has more advantages than the range-only or angle-only measurement scheme. The relative position estimation error on a single axis is within 5 m (3σ).

Key words: aircraft formation, relative navigation, observability analysis, consensus unscented Kalman filter (CUKF)
