Attitude Consensus Tracking Control for Networked Uncertain Rigid Spacecraft with Prescribed Performance

In this study, we tackle the challenge of achieving attitude consensus tracking control for multi-spacecraft system, each spacecraft to uncertainties and operating under a directed network topology. This approach distinguishes itself from conventional methods by eliminating the need for specific initial conditions, thereby ensuring global tracking outcomes that are independent of such conditions. Additionally, we ensure that output consensus tracking is realized asymptotically, while adhering to any predetermined transient performance criteria within a finite time frame. The advancements presented herein are made possible through the utilization of a performance function coupled with prescribed-time observer.
