This paper presents the theoretical and experimental development of an autopilot for the Royal Thai Air Force (RTAF) aerial target. Since there was no prior information about the aerodynamic coefficients and propulsion model, an equation-error method was used to estimate aerodynamic and propulsion coefficients from flight data in order to develop a six-degree-of-freedom (6-DOF) nonlinear mathematical...
A real-time collision avoidance algorithm is developed based on parameterizing an optimal control problem with B-spline curves. The optimal control problem is formulated in output space rather than control or input space, this is feasible because ofthe differential flatness of the system for a fixed wing aircraft. The flat output trajectory is parameterized using a B-spline curve representation. In...
Motivated by the onboard pilots' responsibility and capability to safely return to a cleared route as soon as a resolution advisory is over, this paper first presents a simple framework to integrate a return-to-route system with a collision avoidance system, in which the automation problem for return-to-route maneuvers is formulated. A method, based on the Analytical Hierarchy Process for multi-criteria...
