A Novel Attitude-Tracking Control for Spacecraft Networks With Input Delays

This article is concerned with the attitude synchronous tracking control of time-delayed multispacecraft systems. The attitude-tracking error dynamics are transformed into a modified one that can be readily constructed by the Takagi-Sugeno (T-S) fuzzy approach, where a variable related to system states is treated as the equivalent disturbance. A novel fuzzy-based controller is proposed to guarantee that attitude-tracking systems of multiple spacecraft could be synchronously stabilized with H∞performance. The presented fuzzy-based controller shows its significant advantages compared with the conventional nonlinearity compensation controller. Some improved sufficient conditions ensuring the synchronous stability with H∞performance of large-scale multispacecraft systems are derived. Numerical examples are finally reported to illustrate the efficiency and improved performance of the presented theoretical approaches.
