Systematic Fault Tolerant Control Based on Adaptive Thau Observer Estimation for Quadrotor Uavs [PDF]
Abstract A systematic fault tolerant control (FTC) scheme based on fault estimation for a quadrotor actuator, which integrates normal control, active and passive FTC and fault parking is proposed in this paper. Firstly, an adaptive Thau observer (ATO) is presented to estimate the quadrotor rotor fault magnitudes, and then faults with ...

Robust Reduced Order Thau Observer With the Adaptive Fault Estimator for the Unmanned Air Vehicles [PDF]
Developing fault detection and diagnoses algorithms for the unmanned air vehicles such as the quadrotors is challenging since they are intrinsically non-linear, time-varying, unstable, and uncertain.

Sliding Mode Thau Observer for Actuator Fault Diagnosis of Quadcopter UAVs
Fault diagnosis (FD) is one of the main roles of fault-tolerant control (FTC) systems. An FD should not only identify the presence of a fault, but also quantify its magnitude and location.
