摘要：

This paper investigates the attitude fault-tolerant stabilization problem for a spacecraft subjected to its actuator effectiveness loss, inertia uncertainties and space disturbances. A novel Iterative Learning Sliding Mode Observer (ILSMO) is proposed to reconstruct the actuator effectiveness factors robustly and accurately by combining the P-type iterative learning algorithm with the sliding mode approach. Based on the reconstructed fault signals, an Iterative Learning Sliding Mode Controller (ILSMC) is designed to guarantee the closed-loop spacecraft attitude fault-tolerant stabilization by compensating for its lumped disturbance. The ILSMO and ILSMC sta-bilities are guaranteed using the Lyapunov direct approach, respectively. Finally, the numerical simulation results show that the pro-posed ILSMO-ILSMC-based spacecraft attitude fault-tolerant stabilization method is effective and superior.& COPY; 2023 COSPAR.
