The nonlinear observer-based fault diagnosis method for the high altitude airship

Electronic Research Archive
We investigated an observer-based fault diagnosis method for the high altitude airship (HAA). The nonlinear kinematics and dynamics model, which considers model uncertainties and external disturbances, were obtained. The nonliear portion of the model was

Entangled Multistable Origami with Reprogrammable Stiffness Amplification and Damping

Advanced Functional Materials, EarlyView.
This study introduces a class of origami‐inspired metamaterials that overcome the limitations of existing multistable metamaterials by eliminating the need for rigid lateral confinements. Panel entanglement, snap‐through interactions, and instabilities synergy enable them to achieve extensive shape‐shifting, enhanced stiffness, and remarkable energy ...
