A Robust Adaptive One‐Sample‐Ahead Preview Super‐Twisting Sliding Mode Controller
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 ...

The tribological behavior of 100Cr6 steel spheres textured via Vickers microindentation is evaluated under lubricated sliding by varying both dimple size and density. Fine and dense textures significantly reduce friction across all lubrication regimes, while large dimples increase it.

Theoretical Design and FPGA-Based Implementation of Higher-Dimensional Digital Chaotic Systems
Traditionally, chaotic systems are built on the domain of infinite precision in mathematics. However, the quantization is inevitable for any digital devices, which causes dynamical degradation.

Mathematical modeling of continuous dynamic systems
AbstractMathematical models of physical systems assume several forms depending on their intended use. This paper illustrates the use of a nonlinear and linear model to describe the dynamic response of a particular physical system. A block oriented simulation program, TUTSIM, is presented as the vehicle for obtaining approximate solutions of the ...

A numerical model resulting from irreversible thermodynamics for describing transport processes is introduced, focusing on thermodynamic activity gradients as the actual driving force for diffusion. Implemented in CUDA C++ and using CalPhaD methods for determining the necessary activity data, the model accurately simulates interdiffusion in aluminum ...

Mathematical modeling and simulation of robotic dynamic systems
The mathematical model of the robot generally consists of a nonlinear multi-link system, so varioussimplifications are used in the analysis of its properties. In particular, linear models of robots and controlsystems are commonly used to study the controllability and robustness of robots. In this case, linearmodels are built on the edges of the actions

The Lax-Oleinik semi-group: a Hamiltonian point of view
The Weak KAM theory was developed by Fathi in order to study the dynamics of convex Hamiltonian systems. It somehow makes a bridge between viscosity solutions of the Hamilton-Jacobi equation and Mather invariant sets of Hamiltonian systems, although this
