The theory analysis of this review is applied to the task of controlling and maneuvering the
quad-rotor. The singular four rotor flying vehicle is designed, optimized and applied to the …

This work considers the fractional order control of a lightweight quadrotor under loss in the
battery voltage. Since the outdoor brushless motors are driven via a pulse width modulation …

The automatic landing of a quadrotor is often associated with model uncertainties,
measurement noises, and ground effect phenomenon. To mitigate these challenges, the …

The article focuses on different aspects (both theoretical and practical) of the development of
the control algorithm of a quadrotor helicopter starting from the modelling phase. A new …

The focus of this thesis is the application of the extended Kalman filter to the attitude control
system of a four-propellers unmanned aerial vehicle usually known as quadrotor. The …

In this paper an improved approach is presented for integrating backstepping control of
outdoor quadrotor UAVs. The controller uses the approximated nonlinear dynamic model …

The sensory system of an indoor quadrotor helicopter usually includes several types of
sensors. This paper focuses on the case, where the helicopter has onboard inertial …

The control of autonomous unmanned ground (UGV) and air (UAV) vehicles are part of the
non-linear dynamic control methods. It integrates the knowledge of various fields, and its …

This article focuses on the sensor and actuator system of an autonomous indoor quadrotor
helicopter. The sensor system has two parts: an inertial measurement unit (IMU) and a vision …

A miniature quadrotor helicopter is an underactuated nonlinear system. Usually several
types of sensors are used to control it. This article focuses on the emergency situation, when …
