초록

Aiming at the problem that the shear wind interference makes the aerodynamic load larger when the new generation launch vehicle passes through the windy area, a multi-loop self-adaptive active load relief control method is proposed. Based on the overload feedback load relief method, the observer compensation loop is introduced, and the influence of the multi-loop joint load relief control method on the aerodynamic load and the control load is derived. An adaptive gain real-time scheduling algorithm based on aerodynamic estimation is designed. The simulation evaluation results show that the multi-loop adaptive load relief control method has better adaptability to shear wind interference than the overload feedback load relief control method, which can further improve the load relief ability.
