The quadrotor is an ideal platform for testing control strategies because of its non-linearity
and under-actuated configuration, allowing researchers to evaluate and verify control …

Based on nonsingular terminal sliding mode control (NTSMC), a flight controller is proposed
in this paper for a quadrotor with a total rotor failure. The proposed method is a finite-time …

The mechanical simplicity, hover capabilities, and high agility of quadrotors lead to a fast
adaption in the industry for inspection, exploration, and urban aerial mobility. On the other …

Abstract Unmanned Aircraft Systems (UASs) have advanced technologically and surged
exponentially over recent years. Currently, due to safety concerns, most civil operations of …

Unmanned air vehicles are intrinsically non-linear, unstable, uncertain, and prone to a
variety of faults, most commonly the motor faults. The main objective of this paper is to …

Fault-tolerant control is crucial for safety-critical systems, such as quadrotors. State-of-art
flight controllers can stabilize and control a quadrotor even when subjected to the complete …

This paper proposes a novel adaptive sliding-mode-based control allocation scheme for
accommodating simultaneous actuator faults. The proposed control scheme includes two …

The detection and accommodation of actuator faults in control systems have received
considerable attention. However, the existing fault-tolerant control techniques typically …

This paper presents a relaxed definition of hover for multicopters with propellers pointing in
a common direction. These solutions are found by requiring that the multicopter remain …

In this paper, an emergency fault-tolerant controller is developed for quadrotor unmanned
aerial vehicles (UAVs) suffering a total loss of one actuator (rotor/motor). The proposed …
