通过多模型和扩展的高增益观测器对六旋翼飞行中作动器故障进行恢复

In-flight actuator failure recovery of a hexrotor via multiple models and extended high-gain observers

Connor J. Boss, Vaibhav Srivastava

摘要:

研究了六旋翼无人机飞行中舵机故障恢复问题。六旋翼可能会遇到外部干扰和建模误差,这些干扰和误差在控制设计中被考虑,并与致动器故障区分开来。任何一个执行器的故障发生在飞行过程中,必须快速准确地识别。这是通过使用一个多模型,多个扩展的高增益观测器(EHGO)的输出反馈控制策略。该系列的EHH负责估计状态,干扰,并用于选择适当的模型的基础上系统的动态故障发生后。对所提出的方法进行了理论分析,并通过仿真和实验进行了验证。

英文摘要:

We study an in-flight actuator failure recovery problem for a hexrotor UAV. The hexrotor may experience external disturbances and modeling error, which are accounted for in the control design and distinguished from an actuator failure. A failure of any one actuator occurs during flight and must be identified quickly and accurately. This is achieved through the use of a multiple-model, multiple extended high-gain observer (EHGO) based output feedback control strategy. The family of EHGOs are responsible for estimating states, disturbances, and are used to select the appropriate model based on the system dynamics after a failure has occurred. The proposed method is theoretically analyzed and validated through simulations and experiments.
