Quadrotors are Vertical Take-Off and Landing aerial vehicles with many potential
applications ranging from mapping to supporting rescue operations. This paper aims to …

In this paper, a new robust control strategy based on a predictor and the uncertainty and
disturbance estimator is developed for a class of uncertain nonlinear systems with …

Dead-time processes are common in industry and represent a challenge for feedback
control. The use of predictor structures with the controllers can attenuate this. A predictor is …

In this paper, we consider the inertial measurement units (IMUs) based attitude estimation, a
common core problem in a large variety of robotic systems. In particular, we focus on the …

This thesis deals with the predictive control of uncertain linear systems in presence of
unknown and time-varying input delays. Some observation solutions are proposed to …

Dead time processes are common in the industry and represent a challenge for control. One
way to avoid (or attenuate) the problem is to use a predictor structure alongside the …

For the visual navigation system of unmanned aerial vehicles (UAV), it is of importance to
estimate the relative time delay between camera and inertial measurement unit (IMU) …

Drones are being used in an increasing number of civilian applications. The quadcopter is a
type of drone which has undergone extensive research making it an excellent testbed for …

Disturbances and uncertainties make very difficult the control of Unmanned Aerial Vehicles
(UAV). The problem is even worse, if delays are involved in the process. The uncertainty and …

This works deals with the problem to stabilize a Quad rotor-UAV in presence of time-delay
and disturbances. The proposed controller is based on the reduction approach, ie the …
