In this paper the hexarotor dynamic model with nonlinear inputs and full state back stepping technique is presented. Dead zone and saturation nonlinear inputs are considered reflected to the rotors. The goal is to obtain a faithful mathematical representation of the mechanical system for analysis and control design, not only in hover, but also in motion when take-off, land and flight for aerial navigation...
The system modeling and controller design for air-breathing hypersonic vehicles have always been one of the most highly challenging tasks to the development of hypersonic flight technologies due to the unique characteristics of the vehicle dynamics. In this paper, we first provide an overview of three major classes of control-oriented models of air-breathing hypersonic vehicles in existing literatures...
The ramjet is a new type propulsion system for high-speed flight test aircraft. The ultimate success of sustained high-speed flight will depend on configuring a fine and stable attitude flight control and robust airframe-propulsion-control combination. The mathematical models of high-speed aerodynamic forces and moments were established. A bank-to-turn autopilot structure was used for the longitudinal...
