基于线性规划的多操纵面重构控制研究

Research for multi-control-effector reconfigurable control based on linear programming

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。

To solve the problem of reconfigurable control with multi-control-effector and enhance its flight safety,a flight control design strategy based on linear programming is presented.The reconfigurable control allocators which are used in the typical fault types including deadlock,flabbiness and damage of control surfaces,are derived.And a direct allocation technique based on linear programming is adopted in the design of reconfigurable control allocator.The simulations demonstrate that,the control strategy can deal with typical failures of control effectors and the control commands can be still tracked with relative good handling qualities under control effectors failures.
