This paper focuses on the fault tolerant control for a quadrotor. In this paper, both a complete
dynamic model of quadrotor and a simple reconfigurable PID controller are presented …

This paper addresses the Fault Detection and Isolation (FDI) of the problem of multiple non-
concurrent faults on actuator and sensor of quadrotors, which is described by a nonlinear …

In this paper, we propose a Fault Tolerant Control (FTC) strategy for a reconfigurable
quadrotor with foldable arms, to deal with a total loss of one of its rotors. The proposed …

This paper presents a technique of FDI and FTC based on Thau observers and flatness
theory. The Thau observer allows to estimates the outputs of the system (sensor outputs) to …

Variable pitch quadrotors can experience actuation faults and failures of two main types: one
type related to the rotor system and the other one related to the blade pitch servo. In this …

This paper deals with the active fault-tolerant control (FTC) of a quadrotor in the presence of
actuator faults. Generally, it is assumed that the fault has been detected, isolated or …

This paper addresses the problem of fault detection and isolation (FDI) for a miniquadrotor.
First a model for a four-rotor rotorcraft is presented whose model is obtained via a Lagrange …

This paper proposes a new Fault Tolerant Control (FTC) system for quadrotorswhich are
subjected to actuator loss of effectiveness faults. The proposed FTC system is composed of …

Fault Detection and Identification (FDI) monitor, identify, and pinpoint the type and location of
system fault in a complex multiple input multiple output (MIMO) non-linear system. A …

This paper presents a method for fault detection and diagnosis of actuator loss of
effectiveness for a quadrotor helicopter. This paper not only considers the detection of the …
