–In this paper, first the transfer function and block diagram model of a flight path rate demand autopilot (two loop) in pitch plane has been shown and then its state model has been developed. Then state feedback controller has been designed. Thereafter both of Luenberger and Das & Ghosal Observers (DGO) are implemented for the above said two loop autopilot. Finally the system, observer and sta...

This article addresses the development and experimental validation of a trajectory-tracking control for miniature autonomous Quadrotor helicopter system (X4-prototype) using robust algorithm based on second-order sliding mode technique or also known as super-twisting in outdoor environments. nonlinear strategy guarantees convergence finite time to desired path r(t) presence external disturbance...

This paper presents the air-to-air missile autopilot design for a 180° heading reversal maneuver during boost-phase. The missile’s dynamics are linearized at a set of operating points for which angle of attack controllers are designed to cover an extended flight envelope. Then, angle of attack controllers are designed for this set of points, utilizing a pole-placement approach. The controllers’...

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...

This paper is about the background of two new ideas from neuroeconomics for understanding habits. The main idea a two-process ‘neural autopilot’ model. model hypothesizes that contextually cued habits occur when reward habitual behavior numerically reliable (as in related models with an ‘arbitrator’). computational lightly parameterized, has essential ingredients established animal learning and...

paper presented below is analysis of fuzzy logic controller is carried out and proven that it is best suitable for autopilot system design. Modern day aircrafts heavily rely on automatic control systems for most of the functions and there is always a persistent demand for efficient controllers. There are already many control techniques and methods developed in the field of control engineering, ...

This paper describes an intelligent autonomous airborne flight capability that is being used as a test bed for future technology development. The unmanned air vehicles (UAVs) fly under autonomous control of both an onboard computer and an autopilot. The onboard computer provides the mission control and runs the autonomous Intelligent Controller (IC) software while the autopilot controls the veh...
