Airborne wind energy systems with a rotary wing and a ground generator are analyzed. These systems are very attractive from practical point of view, because of absence of tether drag, simplicity of control, launch and landing of the wing, combined with the well known benefits of AWES, including ability to reach high altitude winds and to adjust altitude dynamically to catch the strongest wind. ...

_ Inverted pendulum control is one of the fundamental and interesting problems in the field of control theory. This paper describes the steps to design various controllers for a rotary motion inverted pendulum which is operated by a rotary servo plant, SRV 02 Series. Nonlinear model of the rotary inverted pendulum and linear model (Upright) in the neighborhood of an equilibrium state are descri...

The purpose of this paper is to present the design of a complete control strategy for the classical and rotary single inverted pendulum system. The design, which involves swing-up and stabilization of both systems, is based on function blocks and GUI tools from the Inverted Pendula Modeling and Control, a Simulink block library developed by the author of the paper. Keywords—classical single inv...

A helicopter is not possessed of an ability to fly fast compared with fixed-wing counterparts. This is a result of considerations with the main rotor. The main rotor moves in a direction very close to its plane of rotation which naturally divides it into two halves which operate under different aerodynamic conditions. One side (called the advancing side) has the rotation and translation velocit...

Nickel-titanium (NiTi) instruments are commonly used for shaping the root canal system in endodontic practice. They are more flexible and have better cutting efficiency than conventional stainless steel files. The superelasticity of NiTi rotary files allows the clinicians to produce the desirable tapered root canal form with a reduced tendency to canal transportation and instrument fracture. Hy...

Tonic immobility (TI) is an innate defensive behavior that can be elicited by physical restriction and postural inversion and is characterized by a profound and temporary state of akinesis. Our previous studies demonstrated that the stimulation of serotonin receptors in the dorsal raphe nucleus (DRN) appears to be biphasic during TI responses in guinea pigs (Cavia porcellus). Serotonin released...
