摘要：讨论了一种新型的鲁棒容错控制器在飞控系统中的应用。该鲁棒容错控制器由两部分组成,主控制器和补偿控制器。首先,建立了飞机的正常标称模型,通过比较标称模型和实际系统的输出生成残差。在飞机无故障情况下,残差近似为零,仅主控制器作用,保证系统在无故障时具有良好的性能;考虑执行机构故障,飞机发生故障后,故障残差不再为零,补偿控制器以残差为输入,输出补偿控制信号,保证系统稳定,补偿故障对系统的影响。仿真结果表明了该新型鲁棒容错控制器的正确性和可行性。
A new robust fault-tolerant controller which could be used in a flight control system was discussed. This controller contained two controllers. One was the main controller and the other was the compensator. First, a normal airplane was modeled. Fault detection residual was generated by comparing the output of the normal model and actual flight system. When there was no fault, the fault detection residual was nearly zero. Only the main controller which was carried out by the aero control surface worked to guarantee a good performance of the system. Once an actuator fault happened, the residual that was the input of the compensator would jump suddenly. Then a compensator which was carried out by the thrust vector was used to guarantee the stability of the whole system. At last, the simulation results showed the feasibility and validity of the new controller.
