飞行控制律的状态观测器重构研究

飞机在飞行过程中，因某些测量元件出现故障致使信号丢失，会严重影响飞行控制系统的正常工作。针对这一问题，提出了设计降维状态观测器进行控制律重构的方法；应用这种方法研究了某无人飞机俯仰通道的控制重构；并对其工程实现进行了探讨。仿真结果表明：引入状态观测器后，习行控制系统在测量元件出现故障时，仍能继续正常工作，并具有较好的动态性能，最后验证了该方法的有效性、可行性。

Study on reconfiguration of flight controllaw using state-observer

Some failing measuring components may lead the loss of signal, and work seriously on the flight control system during the flight. Arming at this problem, the design method of low order observer for flight control reconfiguration is presented. Applying this approach to the pitching channel of a unmanned aircraft, its control law reconfiguration is studied. At the end, its engineering implements are also discussed. The simulating results show that the performance of FCS is very well by introducing the state observer, and the proposed approach is effective and feasible.
