Conventional aircraft use mechanical air brakes to adjust their descent paths; however, the
lift-drag ratio cannot be continuously controlled, which results in zigzag descent paths …

Force exertion, object manipulation, and interaction are novel trending research topics of
autonomous flying robots that can yield hoovering. Moreover, specifically with quadrotors …

The objective of this study was to achieve thrust control of a propeller propulsion system with
two rotor blades rotated by a motor. Previously reported thrust control methods employ …

Research and development have been very active in electric airplanes (EAs). EAs use
electric motors as the power source; therefore, EAs are expected to achieve more secure …

To address the challenge of limited flight duration in drones, research into in-flight inductive
power transfer has emerged as a crucial solution. In this regard, optimizing the flight …

The control performance of a propeller propulsion system depends on its rotor thrust control
performance. When a rotor thrust controller that includes a constant-thrust-coefficient model …

Contact-force control of aircraft involves aerial tasks that require making contact with other
objects. Conventional contact-force controllers for propeller-driven systems utilize a contact …

The contact-force control of propeller driven systems accomplishes aerial tasks that require
making contact with other objects. In these tasks, a disturbance generated by a contact-force …
