A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
International Journal of Adaptive Control and Signal Processing, EarlyView.Block Diagram of the Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller. ABSTRACT This article introduces a discrete‐time robust adaptive one‐sample‐ahead preview super‐twisting sliding mode controller. A stability analysis of the controller by Lyapunov criteria is developed to demonstrate its robustness in handling both ...

Energy flux measurement from the dissipated energy in capillary wave turbulence [PDF]
, 2013 We study experimentally the influence of dissipation on stationary capillary wave turbulence on the surface of a fluid by changing its viscosity. We observe that the frequency power law scaling of the capillary spectrum departs significantly from its ...

The vector power-law calculus with applications in power-law fluid flow
Thermal Science, 2020 In this article, based on the Leibniz derivative and Stieltjes-Riemann integral, we suggest the vector power-law calculus to consider the conservations of the mass and angular momentums for the power-law fluid.
