This article presents a review on the platform design, dynamic modeling and control of hybrid Unmanned Aerial Vehicles (UAVs). For now, miniature UAVs which have experienced a tremendous development are dominated by two main types, i.e., fixed-wing UAV and Vertical Take-Off and Landing (VTOL) UAV, each of which, however, has its own inherent limitations on such as flexibility, payload, axnd endurance...
In this paper, a complete system identification process for identifying flight dynamics model of MAVs (miniature aerial vehicles) is presented. CIFER identification toolkit, which is developed by NASA Ames research center and particularly suitable for identifying rotary-wing aircraft dynamics, is adopted. The modeling procedure is detailed by addressing the following four key steps: 1) data collection...
We document in this article a general introduction to modern miniature unmanned rotorcraft systems. More specifically, we present a fairly detailed overview on the hardware configuration, software integration, aerodynamic modeling, automatic flight control system, and computer vision system involved in forming an unmanned rotorcraft system.
The primary focus of this work is to design and implement a robust automatic flight control system for a smallscale unmanned helicopter. A comprehensive nonlinear model for the unmanned system, which is constructed by our research team at the National University of Singapore, is first derived and presented. Based on its linearized model, a robust automatic flight control system is then designed by...
We present in the paper the comprehensive design procedure of a mini UAV helicopter, called BabyLion. The hardware construction, along with the selection of all of necessary components, will be introduced. Since the system identification method is only partially suitable for the self-built BabyLion, we propose a more suitable parameter identification approach which combines both system identification...
