Disturbance Rejection Attitude Control for a Quadrotor: Theory and Experiment
International Journal of Aerospace Engineering, 2021 In this article, an attitude tracking controller is designed for a quadrotor unmanned aerial vehicle (UAV) subject to lumped disturbances. Firstly, the attitude dynamical model of the quadrotor under external disturbances is established. Subsequently, an

Current understanding of the role of the cell wall in Cuscuta parasitism. [PDF]
Plant Biol (Stuttg)We comprehensively summarise the roles of plant cell wall in key processes of parasitism by the obligate stem parasite Cuscuta. Abstract The plant cell wall (CW) plays a crucial role in many aspects of parasitism by the obligate stem parasite, Cuscuta. Cuscuta parasitism begins with tight coiling around the host stem by the strong tensile force of the ...
