Event-triggered coordinated attitude method for chip satellite cluster

Fault Diagnosis and Prognosis for Satellite Formation Flying: A Survey

“…Spacecraft have internal communication, so it is challenging to design a trigger condition that excludes Zeno behaviour. Using event-triggered inputs, cooperative attitude control of SFFs is pointed in [38]. The interaction between satellites, however, is not yet triggered by events.…”

Event-triggered adaptive fault-tolerant attitude synchronization and tracking control of multiple rigid bodies with finite-time convergence

“…Shen et al (2019) and Ye et al (2018) have considered the coordinated control of the multi-agent system in presence of actuator fault, but the finite-time convergence and nonlinear dynamic model have not been discussed. As opposed to this study, although Guo and Zhang (2019), Zhang et al (2018), and Xu et al (2019) study event-based coordinated attitude control of multiple spacecraft and guarantee asymptotic convergence in presence of external disturbance, fault-tolerant capability and finite-time convergence are not considered by them.…”

“…Different from time-triggered control in a periodic manner, ETC updates its states when its event-triggering condition holds, that is, the error between the sampled and the real-time states exceeds a certain threshold value (Wang et al, 2018). Although ETC has been studied on a single vehicle attitude control problem repeatedly (Chenliang et al, 2019; Wu et al, 2018; Liu et al 2020a; Wang et al, 2019b, 2019c; Xing et al, 2017; Tian et al, 2020; Jiang et al, 2019; Ghasemzadeh Ebli and Nekoui, 2019; Xu et al, 2020), more challenging problems arise in the decentralized cooperative attitude control of multiple vehicles (Weng et al, 2016; Guo and Zhang, 2019; Zhou et al, 2018; Liu et al, 2020b; Weng and Yue, 2016; Zhang et al, 2018; Guo et al, 2020; Wang et al, 2020; Xu et al, 2019) where the information of the neighboring vehicles is not continuously available for making each vehicle’s control signal because of decreasing the communication pressure among the vehicles. For example, Guo and Zhang (2019) propose an event-based adaptive coordinated attitude controller for chip satellite cluster.…”

For example, Guo and Zhang (2019) propose an event-based adaptive coordinated attitude controller for chip satellite cluster. Zhang et al (2018) study attitude control of multi-spacecraft based on a novel event-triggered strategy such that the control updating and data transferring among the spacecraft are executed at certain triggering time.…”
