— In this paper, an active fault tolerant controller using Sliding Mode Observers and Sliding Mode Control for fault tolerant control of a quadrotor UAV is proposed. The sliding mode observer estimates online the amount of fault injected in one of the quadrotor motors. The estimated fault information is then used to update the reconfigurable sliding mode(More)
Identifiability of sensor gain faults is studied and a novel approach to fault detection and diagnosis of a class of nonlinear systems is presented. Sensor gain faults are divided into two classes: the conditionally identifiable faults and the conditionally detectable faults. An algorithm is proposed to obtain the number and location of the conditionally(More)
