In this paper, the problem of spacecraft formation attitude control in the presence of state constraints has been investigated. Multiple constraints such as a spacecraft’s forbidden-attitude avoidance and also the maximum allowable spacecraft actuation limit have been considered during their reconfiguration maneuvers. Unlike previous papers, spacecraft formation keeping is also considered along with the station-keeping goal during the mission. This is critical when their relative attitudes with respect to each other become important due to implementation issues such as relative forbidden-attitude avoidance. Virtual structure approach with decentralized coordinated control scheme is utilized to perform both station-keeping and formation keeping for each spacecraft. The aforementioned goals achieved by the proposed proportianal-derivative (PD)-like global formation controller are incorporated with a local optimal controller in a close loop manner. Also, convergence and stability analysis based on continuous-time interior point method is presented to guaranty the proposed architecture performance.
