Change from a resting state to a full launch on any device that has the characteristic of flight and vertical landing is a major challenge when the control system must be designed. In this sense, there are different effects that alter its dynamics. In this paper, an experimental method based on pseudo-random bit signals (PRBS) is proposed to identify the transfer function of a vertical take-off and...
This paper presents an integrated control framework for the simulation and visualization of cooperative missions for unmanned aerial vehicles (UAVs) and unmanned ground vehicles (UGVs). The X-Plane simulator is utilized to simulate vehicle dynamics and visualize experiments in realistic environments, whereas the control algorithms are executed and validated in Matlab/Simulink. A novel approach to...
Oblique cross quadrotors vehicle is a variant of quadrotors, which is more suitable for take photos in the air compared to the conventional cross-shaped quadrotors and the rotary-wing state of Quad Tilt Rotor(QTR) have to take this flight mode. A lot of research work have done about the conventional cross-shaped quadrotors but little about oblique cross quadrotors vehicle. The mathematics model of...
Here we present the development of a nonlinear dynamic model of an industrial quadrotor with on-board attitude control. Based on this model, we show quite simple controllers for the three space coordinates and the leading of the aerial vehicle. At first, the dynamics of movements within 3D-coordinates are modeled and validated separately. All necessary data are determined by flight experiments and...
