摘要:

针对有向图网络拓扑描述下的长僚机结构的无人机编队系统进行研究,在发生有上界未知的执行器故障的情况下,设计并验证了基于分布式自适应滑模观测器的故障估计方法。首先,对于单一系统,引入基于有向图网络拓扑结构的相对输出误差来表征个体信息的交互,并由此设计对应的滑模观测器并加入自适应理论来应对故障上界未知的情况。其次,定义并构造全局误差系统并通过 Lyapunov 理论完成了稳定性和滑模到达条件的证明。最后,通过线性矩阵不等式工具箱解算出所有待设计参数并通过 Matlab 仿真来验证了方法的有效性。

Abstract:

Under the directed network topology,formation of UAVs with leader-follower structure was studied.And a fault estimation method using distributed adaptive sliding mode observer was designed for actuator fault with unknown upper bound.First of all,for each network node,based on the directed network topology,relative output estimation error was introduced to show information exchanges between neighbouring nodes.And a corresponding sliding mode observer was constructed.Then the global error system was defined,and the stability and sliding mode reaching condition was proved by Lyapunov theory.At last,all the parameters to be designed were calculated by the linear matrix inequality toolbox,and the validity of the proposed method was verified by Matlab simulation.

Key words: sliding mode observer, leader-follow structure, actuator fault, fault estimation
