摘要：

The dynamics of large spacecrafts with moving payloads and flexible attachments have characters of nonlinear, strong flexibility and coupling, which increase the difficulty of control system designing. The major difficulty is that the controller has to overcome all the unknown complicated disturbances with limited control torque. A combined control method is presented in this paper for a type of large spacecrafts. In this method, the main dynamics are approximated by an adaptive fuzzy system, the disturbing torques and the approximation errors are observed by an extended state observer and compensated real timely. The simulation results illustrate the effectiveness.
