针对多操纵面飞机故障重构控制分配的实时性问题,提出了一种基于最大方向导数(MDD)不动点迭代和伪逆法混合的多操纵面重构控制分配策略。推导了沿MDD的当前迭代更新增量,给出了具体的设计步骤,并讨论了改进算法的收敛性。通过与其他方法在多操纵面飞机模型中的对比仿真验证,表明了所提出的混合不动点改进方法的快速性和有效性。
Aiming at the real-time problem of control reconfiguration of multi-control plane aircraft, a multi-control surface reconfiguration control assignment strategy based on the combination of fixed point iteration and pseudo-inverse method of maximum directional derivative (MDD) is proposed. The current iteration update increment along the MDD is deduced, and the specific design steps are given, and the convergence of the improved algorithm is discussed. Through the comparison and verification with other methods in the multi-control aircraft model, the proposed method is fast and effective.
