Modeling and Flight Control of Small UAV with Active Morphing Wings

Research Abstract

In recent research works, morphing wings were studied as an interesting field for a small unmanned aerial vehicle (UAV). The previous studies either focused on selecting suitable material for the morphing wings or performing experimental tests on UAVs with morphing wings. Though, the dynamic modeling of active flexible morphing wings and their involved interactions with the aerodynamics of the UAV body are challenging subjects. Using such a model to control a small UAV to perform specific maneuvering is not investigated yet. The dynamic model of UAV with active morphing wings generates a multi-input multi-output (MIMO) system which rises the difficulty of the control system design. In this paper, the aeroelastic dynamic model of morphing wing activated by piezocomposite actuators is established using the finite element method and modal decomposition technique. Then, the dynamic model of the UAV is …

An Efficient Hyperdimensional Computing Paradigm for Face Recognition

Research Abstract

In this paper, a combined framework is proposed that includes Hyperdimensional (HD) computing, neural networks, and k-means clustering to fulfill a computationally simple incremental learning framework in a facial recognition system. The main advantages of HD computing algorithms are the simple computations needed, the high resistance to noise,and the ability to store excessive amounts of information into a single HD vector. The problem of incremental learning revolves around the ability to regularly update the knowledge within the framework to include new subjects in an online manner. Using an HD computing classifier proved efficient and highly accurate to implement an incremental learning framework as no re-training was required after each online update to the framework wbich is HD computing biggest advantage. Another advantage is that HD computing classifiers can achieve a high degree
