Robust Fault Diagnosis for a Quadrotor with Actuator Fault

International Journal of Engineering and Technology, 2018
Background/Objectives: Fault diagnosis (FD) is a main role in active fault tolerant control system. It can not only determine the location but also estimate the magnitude of fault. Methods/Statistical analysis: This article presents an adaptive fault diagnosis approach for a quadrotor with a simulated actuator fault.
