CONTROLS FOR A SMALL-SIZED VERTICAL TAKEOFF AND LANDING AIRCRAFT DURING TRANSIENT FROM ONE FLIGHT CONDITION TO ANOTHER
Journal Title: Авиационно-космическая техника и технология - Year 2012, Vol 3, Issue 90
Abstract
This paper presents a new class of small vertical takeoff and landing (VTOL) aircraft, also the control algorithms were proposed, which provide a given quality of performance of the studied flying vehicle in nominal condition as well as in presence of abnormal situations. Presents a series of mathematical models, which reflect the peculiarities of the small-sized vertical takeoff and landing aircraft in various of transient condition during changing its trajectory. Also control algorithms were synthesized VTOL during transient condition, capable parry a variety of disturbances.
