摘要:

针对角速度传感器不可用的多无人机协同控制问题,提出一种基于强化学习的固定时间最优姿态控制方法。首先,设计基于神经网络的固定时间观测器,仅需姿态测量信息即可精确重构角速度信号,解决了传感器缺失状态估计难题。其次,结合强化学习理论,提出一种基于分布式观测器的姿态一致性最优控制器,实现跟踪误差的快速收敛。进一步地,基于Lyapunov稳定性理论,严格证明了所提控制方案的固定时间收敛性。最后,仿真结果表明,所提方法可在固定时间内精准重构角速度信号,稳定实现多无人机角度跟踪与姿态一致性控制,降低了传感器缺失对多无人机姿态协同控制的不利影响,同时验证了所设计控制器的有效性和鲁棒性,进一步说明了其在实际应用中的可行性。

Abstract:

Aiming at the problem of cooperative control of multiple quadrotors when the angular velocity sensors are unavailable, a fixed-time optimal attitude control method based on the reinforcement learning is proposed. Firstly, a fixed-time observer based on a neural network is designed. It can accurately reconstruct the angular velocity signal only with the attitude measurement information, thus solving the difficult problem of state estimation in the absence of sensors. Secondly, combining the reinforcement learning theory, an attitude consensus optimal controller based on a distributed observer is proposed, which achieves the rapid convergence of the tracking error. Furthermore, based on the Lyapunov stability theory, the fixed-time convergence of the proposed control scheme is rigorously proven. Finally, the simulation results demonstrate that the proposed method can accurately reconstruct the angular velocity signals within a fixed time, stably achieve multi-quadrotor angle tracking and attitude consensus control, and mitigate the adverse impacts of sensor absence on the attitude cooperative control of multi-quadrotor systems. Meanwhile, the effectiveness and robustness of the designed controller are verified, which further illustrates its feasibility in practical applications.
