Abstract
This research concerns a novel micro-ducted-fan aircraft. A structured attitude controller is designed for a novel unmanned aerial vehicle in the presence of strong state coupling and system pertur...

With the development of automatic flight control technologies, autonomous aircraft has become a focus of society and academic institutions
Before executing the controller design, we present control targets for the closed-loop system: (1) the system should be settled with minimum overshoot and minimum state coupling, (2) the outer-loop responses should be settled within approximately 2 s to ensure satisfactory performance in practice and (3) the gain of the inner-loop controller should remain between 10 and 30 rad/s to ensure sufficient system sensitivity
We present a novel ducted-fan unmanned aerial vehicles (UAVs) for practical performance improvement
Summary
With the development of automatic flight control technologies, autonomous aircraft has become a focus of society and academic institutions. The most common unmanned aerial vehicles (UAVs) have had an open-rotor structure; this design may not satisfy the current requirements. The working environment and conditions are becoming increasingly challenging. UAVs may be required to enter rooms indoors or operate in other complex indoor conditions instead of operating in open-air situations only. The inherent limitations of traditional open-rotor UAVs are expected to become an obstacle hindering further practical application. We propose a novel tandem micro-ducted-fan UAV with strong potential in complex working conditions. The inherent advantages of the novel UAV are as follows
