A comprehensive design procedure based on extremum seeking for minimum power demand formation  ight is presented, the Ž rst with performance guarantees. The procedure involves the design of a new wake robust formation hold autopilot and transformation of the closed-loop aircraft dynamics to a form in which a newly available rigorous design procedure for extremum seeking is applicable. The desi...

This paper is concerned with autopilot design for an agile missile with aerodynamic fins, thrust vectoring control, and side-jet thrusters. Two-time scale dynamic inversion is used as a nonlinear flight control law. To deal with the inherently weak robustness property of dynamic inversion, Ackermann-like formula which is a time-varying version of Ackermann formula for LTI systems is applied to ...

This paper describes the use of FlightGear, an open-source flight simulator, and JSBSim, an open source flight dynamics model, to model and simulate a small autonomous Unmanned Aerial Vehicle (UAV). A small commercial electric engine Cessna-182 radio controlled (RC) aircraft was chosen to represent the UAV. The first step was to create the required JSBSim aircraft configuration files by using t...

A cooperative autopilot is developed for the control of the relative attitude, relative position, and absolute attitude of two maneuvering spacecraft during on orbit proximity operations. The autopilot consists of a open-loop trajectory solver which computes a nine dimensional linearized nominal state trajectory at the beginning of each maneuver and a phase space regulator which maintains the t...

The AERObot is a special ARM microcontroller-based autopilot for small and medium size UAVs 1 developed at Óbuda Universtiy for research purposes. The aim of the research was to create a generic autopilot which is capable of controlling different design, weight and structure airframes without any complex parameter or model recalculation as usual for e.g. switching between tailless or classic ta...

In this study, pilots were asked to achieve a specific time in trail while flying an arrival into Louisville International airport. Weather shortly before the start of the descent added variability to the initial intervals. A spacing tool calculated airspeeds intended to achieve the desired time in trail at the final approach fix. Pilots were exposed to four experimental conditions which varied...
