针对通信受限条件下的航天器轨迹跟踪问题,提出了一种基于事件触发的预设时间控制算法。为了满足不同任务场景下对航天器快速性的要求,本文设计了一种预设时间轨迹跟踪控制算法。结合反步控制理论及预设时间动态增益,最终实现轨迹跟踪系统的预设时间收敛。作为一种典型的网络化控制系统,航天器在执行任务过程中可能会受到自身通信能力的限制,造成通信阻塞、时延和丢包等问题。为此,本文提出了一种基于动态参数的事件触发算法,在保证系统控制精度的同时,一定程度上避免了控制中心与航天器本体间不必要的通信资源消耗。相比于传统的静态事件触发算法,文中基于动态参数的事件触发算法在减少通信频率方面更具优势。通过理论分析和仿真实验验证所提控制算法的有效性。
- Abstract:
-
An event trigger-based prescribed-time control algorithm is proposed for trajectory tracking of a spacecraft under communication constraints. First, to endow the spacecraft with rapidity under different task scenarios, a prescribed-time trajectory-tracking control algorithm is designed, which finally achieves the prescribed-time convergence of the trajectory-tracking control system by combining the backstepping control theory and dynamic gain of the prescribed time. Second, as a typical networked control system, the spacecraft may be limited by its own communication capability in the process of task implementation, which will lead to communication congestion, time delay, packet loss, and so on. Therefore, an event-trigger algorithm is proposed based on the dynamic parameter. While assuring system control precision, the algorithm can avoid unnecessary communication consumption between the control center and the spacecraft itself to a certain extent. Compared with the traditional static event-trigger algorithm, the proposed dynamic parameter-based event-trigger algorithm has the advantage of reducing the communication frequency. Finally, the effectiveness of the proposed control algorithm is verified by theoretical analysis and simulation experiments.
