基于事件触发的航天器编队姿态预设时间控制
Event-Triggered Prescribed-Time Attitude Control Method for Spacecraft Formation
摘要
Abstract
To address the issues of uncontrollable convergence time and low resource utilization ef-ficiency in spacecraft formation attitude cooperative control,a prescribed-time sliding mode control method based on rotation matrices is proposed.First,a nonsingular attitude error kinematic and dynamic model is constructed,and a prescribed-time sliding surface is designed to ensure that the system states converge within a predetermined time.Second,to enhance the controller's robustness against system uncertainties,a radial basis function neural network is introduced for online compensation.Simultaneously,a state-dependent event-triggered mechanism is devised to update control commands on demand,significantly reducing network load.Furthermore,the sta-bility of the closed-loop system and the absence of Zeno behavior in the triggering mechanism are rigorously proven via Lyapunov analysis.Finally,simulations on a spacecraft formation system are conducted,and the results demonstrate that the proposed method achieves attitude coordination within 10 seconds while reducing the communication frequency by approximately 94.20％.Com-pared with conventional methods,the proposed control law offers controllable convergence time and exhibits significant engineering value in improving task responsiveness and resource utilization efficiency.关键词
