摘要:

执行机构的物理限制等因素的影响,多飞行器姿态一致性控制面临姿态和角速度约束的挑战,加大了设计有效姿态一致性控制器的技术难度。针对此问题,提出了一种状态约束(含姿态和角速度约束)下的多飞行器有限时间姿态一致性控制器。利用非光滑理论和代数图论的知识设计了一类有限时间姿态一致性控制策略,并结合障碍Lyapunov函数技术构建了一类新颖的姿态一致性跟踪控制器。理论分析表明,提出的控制器能够在满足姿态和角速度约束条件下实现所有飞行器的姿态在有限时间内跟踪到期望姿态值。该方法具备结构简单、自定义约束适应性强和快速收敛等优点。仿真结果表明,所提的方法能够在满足姿态和角速度约束的条件下实现多飞行器对期望姿态的有限时间一致性跟踪。

Abstract:

Due to factors such as the limited capabilities of the actuators, one needs to generally consider the effect of constraints on both attitude and angular velocity when addressing the attitude consensus control problem of multiple unmanned aerial vehicles (UAVs). However, the constraints on both attitude and angular velocity pose a challenge to the design of effective attitude consensus controllers for multiple UAVs. To address such an issue, this paper introduces a finite-time attitude consensus controller for multiple UAVs under state constraints including the constraints on both attitude and angular velocity. Specifically, by using tools from nonsmooth analysis and algebraic graph theory, the paper develops a class of finite-time attitude consensus control strategies. In addition, combined with the barrier Lyapunov function (BLF) technique, it constructs a novel attitude consensus tracking controller. Theoretical analysis demonstrates that, under attitude and angular velocity constraints, the proposed controller enables the attitude of all UAVs to track the desired attitude within a finite time. Notably, the proposed method offers advantages such as simplicity of structure, adaptability to user-defined constraints, and fast convergence. Simulation results indicate that the proposed controller achieves finite-time consensus tracking of the desired attitude under constraints on attitude and angular velocity.
