Robotic and mechatronic systems, autonomous vehicles, electric power systems and smart
grids, as well as manufacturing and industrial production systems can exhibit complex …

This paper shows that the aerodynamic effects can be compensated in a quadrotor system
by means of a control allocation approach using neural networks. Thus, the system …

Various quadrotor drones have been developed in recent years, mainly focusing on either
improving maximum thrust per platform area or flight maneuverability. Evidently, achieving …

Abstract Active Disturbance Rejection Control (ADRC) has recently stood out as a viable
alternative to the proportional–integral–derivative controllers. An interesting field of …

Coaxial rotors used on multirotor Micro Aerial Vehicles (MAVs) are complex aerodynamic
systems that are typically treated in a simplified manner, operating in sub-optimal conditions …

Coaxial multirotors, characterized by overlapping rotors, represent a common solution to
increasing payload capacity while maintaining a compact platform size. However, the …

Control allocation in multirotor unmanned aerial vehicles (UAVs) converts control signals to
commands for individual actuators. Errors may be introduced into the system via inaccurate …

This work carries out an analysis on fault tolerance in multirotor vehicles, particularly for an
hexarotor one, where such feature is achieved by shifting the center of mass in case of a …

The article proposes a nonlinear optimal control approach for the model of the autonomous
octorotor. This aerial drone has improved load transport capability due to being actuated by …

Attitude control in quadrotors usually does not consider the possibility of actuator lossof-
effectiveness, becoming then inefficient at certain operating conditions. Fault-Detection and …
