摘 要:[目的]针对多自主水下航行器(AUV)上装备的惯性导航系统(INS)和多普勒速度计程仪(DVL)失效或未配备的情况,结合传统的扩展卡尔曼­滤波(EKF)估计,提出一种基于双模型的­协同定位方法。[方法]建立AUV相对运动模­型和双领航状态空间模­型,通过水声通信,利用相对运动模型估计­跟随 的速度信息,再应用双领航模式的多­AUV协同定位状态空­间模型,进一步提高协同定位系­统的鲁棒性和准确性,利用海试数据进行半实­物仿真验证。[结果]结果表明,基于双模型的主从式多­AUV协同定位方法,能够在跟随AUV上没­有INS和DVL的情­况下,实时估计跟随AUV的­位置。[结论]该方法能够保障协同定­位系统定位精度在允许­的范围内,降低多AUV协同定位­系统的成本。关键词:自主水下航行器;协同定位;扩展卡尔曼滤波;相对运动模型;水声通信中图分类号:U666.1 文献标志码:A DOI:10.19693/j.issn.1673-3185. 01636

Low-cost multi-AUV cooperativ­e localizati­on method based on dual-model

XU Bo,LI Shengxin*,ZHANG Huan College of Automation,Harbin Engineerin­g University,Harbin 150001,China Abstract:[Objectives] In order to solve the problem of inertial navigation systems(INS) and doppler velocity logs(DVL) on multiple autonomous underwater vehicles (AUV) failing or having no sensors, combined with the traditiona­l extended Kalman filter estimation,a cooperativ­e positionin­g method based on dual-model is proposed.[Methods] A relative motion model and two-leader state space model are establishe­d. The velocity informatio­n of the following AUV is estimated using the relative motion model in underwater acoustic communicat­ion,and then the multi-AUV coordinate­d positionin­g state space model with the two-leader model is applied to further improve the robustness and accuracy of the coordinate­d positionin­g system. Semi-real simulation experiment­s are then carried out using sea test data.[Results] The results show that the leader-follower multi-AUV cooperativ­e localizati­on method based on the dual-model can estimate the position of the following AUV in real time without INS or DVL on the AUV. [Conclusion­s]This method can ensure that the positionin­g accuracy of the cooperativ­e localizati­on system is within the allowable range,and reduce the cost of the multi-AUV cooperativ­e localizati­on system.
