This paper presents the dynamic model of an Unmanned Aerial Vehicle (UAV), specifically, a fixed-wing aircraft PT-40, using extended vectors in ℝ6. This representation of cartesian coordinates in the Euclidian space simplifies the representation of the model to express each term in a single six dimensional vectorial equation, instead of the three dimensional, conventional linear and angular movement...
This paper presents a method to accurately identify the yaw-dynamic model of an unmanned helicopter. First, the model's structure is established by dynamic analysis. Then the model is reconstructed into a combination of three second-order subsystems. As the distribution of the damp ratios and natural frequencies of a second-order subsystems is limited, the model can be accurately identified from real-flight-test...
Aerial robotics provides many practical applications in fields such as search and rescue and surveying. In order to advance the research in aerial robotics, an inexpensive test platform is required. Our four-rotor platform provides researchers with a inexpensive, fully scalable test platform for future studies. Its completely on-board processing removes the need for a virtual tether in the form of...
