摘　　要：双余度舵控系统的基本思想是通过不同余度之间的切换来保证舵控系统的可靠性。针对无人机双余度电动舵机角度传感器故障检测技术提出了基于辨识参考模型的方法。首先介绍了电动舵机的双余度方案,然后通过机理分析和理论推导相结合的方式建立了舵系统的输入输出模型,利用系统辨识的方法确定了模型的参数。最终利用辨识的参考模型对双余度角度传感器进行故障检测,并通过实验,验证了方法的有效性。The basic idea of dual redundancy actuator is to ensure the reliability of actuator by switching between different redun- dancies. In this paper, a method based on the identification reference model is proposed for the fault detection technology of dual redundancy electric actuator of UAV. Firstly, the paper introduces the structure of the dual redundancy actuator, then the model of the actuator system is established through a combination of mechanism and theoretical analysis, and system identification method is used to determine the parameters of the model. Finally, the identified reference model is used to detect the fault of the dual redun- dancy angle sensor, and the effectiveness of the method is verified by the actual experiment.
