摘要

This paper studies multi-spacecraft system attitude consensus control with model uncertainty, sensor faults and time-varying input delay. Attitude dynamics of the spacecraft is described using Euler angles. Predictor-based state transformation method is proposed to get delay-free system states with delay information unknown. Afterwards, descriptor observer is used to estimate system states and sensor disturbances. Disturbance attenuation controller is designed based on system state estimates. Finally, a simulation example demonstrates the system performance under the designed algorithm.
