These kinds of robots are commonly controlled with Proportional-Integral-Derivative (PID) controllers; however, traditional linear controllers have limitations when controlling highly nonlinear and uncertain systems such as UAVs. These different morphing stages are basically analyzed by four different discrete stages with wing quarter sweep angle of 5, 20, 35 and 50 degrees respectively. >>
Worldwide demand for robotic aircraft such as unmanned aerial vehicles (UAVs) and micro aerial vehicles (MAVs) is surging. Unmanned Aerial Vehicles, or UAVs, as they have sometimes been referred to, have only been in service for the last 60 years. In the study, first of all, the determination of natural carriers was performed. This paper describes an empirical analysis evaluating the performances of the unscented Kalman filter and comparing them with the extended Kalman filter's performances. >>

This paper suggests drones as futuristic machinery complimenting the existing workforce in law and order scenario. An unmanned aerial vehicle (UAV) (or uncrewed aerial vehicle, commonly known as a drone) is an aircraft without a human pilot on board. The closed-loop stability of the system arising from the combination of the gradient-descent controllers and the consensus estimators is studied and simulation results are provided to illustrate the proposed theory. For this purpose, 18 different combinations were proposed, varying the number of ground control points (GCPs), the adequacy (or not) of the distribution of GCPs, and the orientation of the photographs (nadir and oblique). The current global pandemic has raised a question in setting the priority of national security over privacy. /Contents 3 0 R
