为实现多操纵面飞机的重构控制,提高飞机飞行的安全性能,提出了一种基于线性规划的多操纵面重构控制策略。针对操纵面卡死、松浮、损伤等典型故障情况,推导了相应的重构分配器,通过基于线性规划的直接分配方法来实现在操纵面故障下的重构控制。仿真结果表明,该控制策略能有效处理典型操纵面故障,发生故障时仍能快速跟踪控制指令,保证较好的飞行性能。
In order to realize the reconfiguration control of multi-control aircraft and improve the safety of aircraft flight, a multi-control surface reconfiguration control strategy based on linear programming is proposed. Aiming at the typical failure conditions such as stuck, loose and damaged control surfaces, the corresponding reconfigurable distributor is deduced, and the reconfiguration control under the control plane fault is realized through the direct allocation method based on linear programming. The simulation results show that this control strategy can effectively deal with the typical control surface faults, and can still track the control commands rapidly in the event of a fault, so as to ensure good flight performance.
