Finite-Time Trajectory Tracking Control for Rigid 3-DOF Manipulators With Disturbances
IEEE Access, 2018 This paper addresses the robust finite-time trajectory tracking control problem for a rigid three-degrees-of-freedom (3-DOFs) manipulator system, which is subject to model uncertainty and external disturbances.

On Condition for Output Finite-Time Stability and Adaptive Finite-Time Control Scheme [PDF]
2019 IEEE 58th Conference on Decision and Control (CDC), 2019 A sufficient condition for output finite-time stability is presented. Based on this condition a scheme of adaptive finite-time control design is provided. The presented results are obtained with the use of homogeneity property. The theoretical results are supported by numerical examples.

Advanced Engineering Materials, EarlyView.Geometry‐driven thermal behavior in wire‐arc additive manufacturing (WAAM) influences microstructural evolution during nonequilibrium solidification of a chemically complex Fe–Cr–Nb–W–Mo–C nanocomposite system. By comparing different deposits configurations, distinct entropy–cooling rate correlations, segregation, and carbide evolution are revealed ...

Advanced Engineering Materials, EarlyView.A combined finite element and phase‐field approach predicts the evolution of microstructure during the directional solidification of Ni‐based superalloys. The model reveals how withdrawal rate, temperature gradient, and wall thickness control the dendrite spacing, highlighting the strong effect of surface regions in thin sections where dendrite growth ...

Improved results on finite time stability of time delay systems: Jensen's inequality-based approach [PDF]
Tehnika, 2018 In this study, finite-time stability of the linear continuous time-delay systems was investigated. A novel formulation of the Lyapunov-like function was used to develop a new sufficient delay-dependent condition for finite-time stability.

Finite-Time Stability and Controller Design of Continuous-Time Polynomial Fuzzy Systems
Abstract and Applied Analysis, 2017 Finite-time stability and stabilization problem is first investigated for continuous-time polynomial fuzzy systems. The concept of finite-time stability and stabilization is given for polynomial fuzzy systems based on the idea of classical references.

Entropy, 2022 In this paper, we study the finite-time stability of permanent magnet synchronous motors (PMSMs) with noise perturbation. To eliminate the chaos in a PMSM and allow it to reach a steady state more quickly within a finite time, we propose a novel adaptive

Finite‐Time Stability and Stabilization of Nonlinear Quadratic Systems with Jumps [PDF]
Mathematical Problems in Engineering, 2014 This paper investigates the problems of finite‐time stability and finite‐time stabilization for nonlinear quadratic systems with jumps. The jump time sequences here are assumed to satisfy some given constraints. Based on Lyapunov function and a particular presentation of the quadratic terms, sufficient conditions for finite‐time stability and finite ...

Advanced Engineering Materials, EarlyView.The wettability of aluminum droplets (Al) on different copper substrates (Cu), where liquid Al spreads on solid Cu surfaces to form a liquid–solid interface, is studied numerically and experimentally. The experimental and numerical results show good agreement in the fast‐spreading regime.
