摘　　要：随着未来航天技术的发展对航天器自主性工作的要求越来越高,星上嵌入式系统所需处理的数据量也急剧增大.而如何在通信与计算资源约束下保证航天器性能就成为一个关键问题.本文基于事件触发控制方法,提出一种在保证控制性能前提下能够大幅降低星上总线负载的航天器姿态控制方法.并从扰动系统理论出发,给出算法的设计流程和稳定性证明.通过仿真算例验证算法的有效性.Future spacecraft will have much autonomous work. And the utilization of embedded system continues growing with data increasing. In this paper,a nonlinear event triggered control approach is applied for the spacecraft attitude control. By this approach,the utilization of bus bandwidth decreases greatly and a good control performance is achieved. Moreover,the design procedure and stability proof of this algorithm are given via perturbation theorem. Finally,a numerical example is provided to illustrate the efficiency and feasibility of the proposed approach.
