This paper details the developments to date of an unmanned air vehicle (UAV) based on a standard size 60 model helicopter. The design goal is to have the helicopter achieve stable hover with the aid of an INS and stereo vision. The focus of this paper is on the development of an artificial neural network (ANN) that makes use of only the INS data to generate hover commands, which are used to dir...

Recent developments in the area of stereoscopic displays and tracking technologies have paved the way to combine touch interaction on interactive surfaces with spatial interaction above the surface of a stereoscopic display. This holistic design space supports novel affordances and user experiences during touch interaction, but also induce challenges to the interaction design. In this paper we ...

Abstract. The design of a static parametric H∞ loop shaping controller using a linear matrix inequality (LMI) approach for a hover system is presented. The main steps to obtain such controller are explained. The parametric H∞ loop shaping technique explores more design flexibility by introducing a free parameter into the design process that ensures robust stabilization with regard to normalized...

Introduction T HE propulsion system of a short takeoff and vertical landing aircraft, such as the F-35 Joint Strike Fighter, must operate over a wide range of conditions, provide good fuel efficiency at cruise, and deliver high thrust in augmented mode for transonic acceleration and supersonic operation. The propulsion system must be efficient for both high-speed flight and during hover, while ...
