Abstract In this paper, the problem of anti-disturbance control for flexible spacecraft with quantized states is investigated. By using quantized states, an extended state observer is constructed to estimate the flexible modal and external disturbances. Then based on the output of extended state observer and quantized states, an anti-disturbance controller is designed via recursive design method. Afterwards, the Lyapunov stability analysis is established to exhibit the boundedness of the closed-loop signals of the spacecraft systems. The merit and effectiveness of the obtained results are verified via simulation comparison.
