In this article, we study the leader-following practical attitude consensus problem of a group of multiple uncertain rigid spacecraft systems over jointly connected networks by a distributed event-triggered control law. We first establish a lemma that allows the problem to be converted to a distributed practical stabilization problem of a well-defined uncertain dynamical system. Then, we combine the adaptive distributed observer technique and the adaptive control technique to design an event-triggered adaptive control law and an event-triggered mechanism to solve our problem. The effectiveness of our design is illustrated by a numerical example.
在本文中,我们通过分布式事件触发控制律研究了一组多个不确定刚性航天器系统在联合连接网络上的领导者跟随实际姿态一致性问题。我们首先建立了一个引理,该引理允许将该问题转化为一个定义明确的不确定动态系统的分布式实际镇定问题。然后,我们结合自适应分布式观测器技术和自适应控制技术,设计了一种事件触发自适应控制律和一种事件触发机制来解决我们的问题。通过一个数值例子说明了我们设计的有效性。
