摘要

针对全液压损失的多电动飞机，提出了一种主动容错控制策略。基于线性二次型调节器(LQR)和模型参考控制(MRC)方法，重新配置容错控制律。将控制面看作独立的控制面，采用了一种新的模型。在没有液压动力的情况下，不同冗余驱动系统(DRAS)将液压致动器(HA)切换为电液致动器(EHA)来驱动控制面。通过对比HA和EHA的不同响应性能，通过受损飞机模型来表征其性能退化。最后，数值模拟结果验证了AFTC策略对总水力损失的有效性。

LQR-MRC active fault tolerant control for more-electric aircraft without hydraulic power

This paper presents an active fault tolerant control (AFTC) strategy for the more-electric aircraft suffering from total hydraulic loss. Based on linear quadratic regulator (LQR) and model reference control (MRC) method, the fault tolerant control law is reconfigured. A new model is adopted by regarding the control surfaces as independent ones. Without hydraulic power, the dissimilar redundant actuation system (DRAS) switches hydraulic actuators (HA) into electro-hydraulic actuator (EHA) to drive the control surfaces. Furthermore, by comparing different response performance of HA and EHA, the performance degradation is represented through the damaged aircraft model. Numerical simulation results validate the effectiveness of proposed AFTC strategy towards total hydraulic loss finally.
