摘要:

针对多无人系统的编队包含控制问题,本文提出一种自适应鲁棒控制方法。针对系统中的领航者层和跟随者层分别设计对应的编队、包含以及避撞行为约束,并由Udwadia-Kalaba方程求得满足约束所需的理想驱动力。通过渐亏型自适应律估计系统的不确定参数,从而补偿不确定性影响。然后,采用李雅普诺夫函数方法验证了所设计控制的稳定性。最后,数值仿真结果显示:含时变不确定性的受控系统在完成编队包含行为的同时无任何碰撞发生。

Abstract:

An adaptive robust control method is proposed for the formation containment control of multiple unmanned ground vehicle system. The behavior constraints including formation, containment and collision avoidance are designed for the leader layer and the follower layer of the system, and the ideal driving force required to meet the constraints is obtained by the Udwadia-Kalaba equation. An adaptive robust control method based on fading adaptive law is proposed to estimate the uncertain parameters of the system so as to compensate for the influence of uncertainty. The Lyapunov function method is used to verify the stability of the designed control. Finally, the numerical simulation results show that the controlled system with time-varying uncertainty completes the formation containment task without any collision.
