Abstract: This paper presents a novel dynamic scaling–based non-certainty-equivalent adaptive control method for the attitude tracking control problem of spacecraft in the presence of inertia uncertainties. By virtue of the modified ...

Abstract: Various plants have the ability to follow the sun with their flowers or leaves via a mechanism known as heliotropism, which is powered by pressure gradients between neighboring motor cells. Adapting this bio-inspired ...

Abstract: This paper investigates the nonlinear responses of a typical twodimensional airfoil with control surface freeplay and cubic pitch stiffness in an incompressible flow. The differential transform (DT) method is applied to ...

Abstract: The characteristics of flow instabilities as well as the cavitation phenomenon in a centrifugal pump operating at low flow rates were studied by experimental and numerical means, respectively. Specially, a threedimensional ...

Abstract: In large low-lift pump stations, the pump assembly comprises an inlet conduit, a pump, and an outlet conduit. A short conical frustum section that connects the elbow section with the impeller inlet directly affects the ...
