Flexible FlappingTo investigate the aerodynamic performance of a flexible flapping wing aircraft, a flapping-wing system were design and an experiment were set up to measure the unsteady aerodynamic forces of th
Papers that describe aspects of the dynamics and control of significant recent developments, such as a new or different aircraft or spacecraft, also are desired. 主办单位: AMER INST AERONAUTICS ASTRONAUTICS 出版地区: United States 出版周期: 月刊 别名: 指导、控制与动力学杂志;JGCD 国际标准连续...
A feedback control design method is proposed based on the Lyapunov stability theory to derive the closed-loop stability conditions. The system dynamics model that includes the aircraft rigid body model, flexible cables, pulleys, springs, aerodynamic model, and servo motor control is established using...
In order to get more solar energy and better flight performance, HALE aircraft are normally built with relatively long and slender high-aspect ratio wings, so the wings of HALE aircraft are very flexible, with large wing deformations during flight. ...
Differential thrust can be used for directional control on distributed electric propulsion aircraft. This paper presents an assessment of flight dynamics and control under engine inoperative conditions at minimum control speed for a typical distributed propulsion aircraft employing differential thrust. A metho...
Time-delay of flight, control systems has great influence on stability and manuverbility of flying vehicles, and it is of practical importance to design a control law with consideration of the estimated time-delay. In this paper, H∞ optimal controller considering time-delay is solved explicitly...

Even though the expression of (A1) and (A2) are similar, there is a difference in meaning. The ERMSE is an extension of RMSE, which aims to measure the performance of machine-learning models, where models take multiple inputs and produce multiple outputs of different scales. The outputs ar...
An operational activity scenario is a time-ordered dynamic flow, on a temporal axis (conventionally vertical from top to bottom), of interactions between different operational activities in the context of implementing a capability.
