Abstract:
<p>The market for vertical takeoff and landing unmanned aerial vehicles, VTOL UAVs, is growing rapidly. To reciprocate the demand of VTOL UAVs in offshore applications, CybAero has developed a novel concept for landing on moving objects called MALLS, Mobile Automatic Launch and Landing Station. MALLS can tilt its helipad and is supposed to align to either the horizontal plane with an operator adjusted offset or to the helicopter skids. Doing so, eliminates the gyroscopic forces otherwise induced in the rotordisc as the helicopter is forced to change attitude when the skids align to the ground

Abstract:
This work presents the application of the Linear Quadratic Tracker (LQT) for the automatic landing system of passenger transport airplanes. The design method to achieve an autoland flare law with improved performance and disturbance rejection is described. With this method the design is direct and more formal thus avoiding the somewhat time consuming and more ad-hoc design iterations currently practice in industry. Although the design technique has been used for a autoland system, the approach is general enough to be used in other control applications. The structure of a traditional flare cont

Fuzzy neural networks can increase the flight controller’s adaptation to different environments. Currently, most of the improvements in the Automatic Landing System (ALS) have involved the guidance instruments. Using improved calculation methods and highly accurate instruments, these systems provide more accurate flight data to the ALS to make the landing smoother. However, these researches do not i

It’s not only hard to recognize the runway from camera in dusk or overcast environments, even at night, but also the pilot is difficult to do visual approach and landing manually. This paper present a computer vision-based automatic landing assistant system for fixed-wing UAV. By recognizing four red runway lights on the edges of the runway to estimate the lateral offset, vertical height, horizontal distance relative to runway head, and three attitude angles. The advantages are to gain flexible usage and

Most of the studies regarding flight control are based on conventional modern control theories with optimal or adaptive control methods. Typically these techniques involve linearizing the aircraft dynamics about several operating conditions through out the flight envelope, designing linear controllers for each condition, and gain-scheduling approach. The disadvantages are that it require extensive computations, memory utilization, and memory space. Furthermore

Abstract:
This work presents a novel real-time algorithm for runway detection and tracking applied to the automatic takeoff and landing of Unmanned Aerial Vehicles (UAVs). The algorithm is based on a combination of segmentation based region competition and the minimization of a specific energy function to detect and identify the runway edges from streaming video data. The resulting video-based runway position estimates are updated using a Kalman Filter, which can integrate other sensory information such as position and attitude angle estimates to allow a more robust tracking of the runway under turbulen

Airplane pilots must not only be acquainted with the operation of instrument boards, but also need flight sensitivity to the ever-changing environment, especially in landing phase when turbulence is encountered. The Automatic Landing system (ALS) can help to alleviate the pilot’s work during landing process but with limited conditions.
