N2 - Aiming at the problem of vibration suppression of flexible spacecraft and high frequency chattering of sliding mode variable structure control torque, a real-time optimization sliding mode variable structure control algorithm based on the intelligent fuzzy method is proposed. Through designing variable structure control strategy with exponential approach law, the spacecraft attitude control and vibration suppression of flexible appendages are achieved. However, the control torque may present high frequency chattering during the sliding phase, and effect of vibration suppression will be weakened. The intelligent fuzzy control algorithm is used to eliminate chattering by optimizing parameters of the control system. Numerical simulations show that the high frequency chattering of control torque is restrained effectively and vibration suppression can be accomplished with faster convergence.
