Adaptive Trajectory Tracking Control of a High Altitude Unmanned Airship

Nonlinear dynamic model of a high-altitude unmanned airship, expressed by generalized coordinate, was built. A nonlinear compensation was introduced into the control loop to linearize and decouple the nonlinear system globally. In view of the imprecisely known inertia parameters of the airship, an adaptive law was proposed based on the feedback linearization to realize asymptotic tracking of an...

A strategy for oxygen conditioning at high altitude: comparison with air conditioning.

Large numbers of people live or work at high altitude, and many visit to trek or ski. The inevitable hypoxia impairs physical working capacity, and at higher altitudes there is also cognitive impairment. Twenty years ago oxygen enrichment of room air was introduced to reduce the hypoxia, and this is now used in dormitories, hotels, mines, and telescopes. However, recent advances in technology n...

Low-altitude Unmanned Airship Photogrammetry System

Constrained by the satellites orbits, Satellite Remote Sensing is difficult to achieve timeliness requirements. General aerial manned aircraft Remote Sensing is always delayed by the bad weather. Compared with Unmanned aerial vehicles, unmanned Airship can fly more lower and slower and you can get more clearer image. So it is more suitable for large scale mapping and other engineering requireme...
