This article is concerned with parameters identification problems and computer modeling of thrust generation subsystem for small unmanned aerial vehicles (UAV) quadrotor type. In this paper approach for computer model generation of dynamic process of thrust generation subsystem that consists of fixed pitch propeller, EC motor and power amplifier, is considered. Due to the fact that obtainment of aerodynamic...
A reconfiguration method using model-based control allocation scheme is proposed in this paper. A reconfigurable closed-loop control system is established for control of a UAV (unmanned aerial vehicle) fixed wing aircraft in autonomous flight in case of single and multiple control surfaces failures. The control allocation is determined by using of a nonlinear dynamic model of a UAV aircraft. The model...
Miniature vertical take-off and landing unmanned aerial vehicles (VTOL UAVs) make various missions possible alone such as surveillance in partially-destroyed building and at broad hazard area where many obstacle exist. In such missions, agile turnaround using post-stall maneuvers is useful to avoid obstacles. This paper discusses agile turnaround strategies utilizing post-stall maneuvers for tail-sitter...
Most UAV flight control system simulation was used for evaluating the quality of UAV and designing it, however, the results failed to conform to actual flight laws. According to the need of UAV simulator in actually, a new way which was convenient for engineering computing and appropriated for simulation training was built for simulating flight control system. With the actual flight figures, flight...
Automatic control of unmanned aerial vehicles (UAVs) has been a growing area of research in aerospace technology for a long time, yet this area needs a great deal of development in order to get a reliable autonomous system capable of performing all types of maneuvers with high degree of stability and desired performance. In this paper, the development and building of a fully functioning test bed UAV...
