摘 要：In this paper, we consider the robust global finite-time coordinated attitude tracking problem for multiple spacecraft with general directed communication graphs. First, a robust global finite-time attitude tracking controller is designed for single spacecraft based on homogeneous control method and integral sliding mode control method. Quaternion representation is used and the undesirable unwinding phenomenon is avoided. Based on the proposed finite-time attitude tracking controller, an observer-based distributed finite-time attitude tracking controller is designed for multiple spacecraft. Simulation examples are provided to demonstrate the obtained results.
