HEPSO-SMC: a sliding mode controller optimized by hybrid enhanced particle swarm algorithm for manipulators

Scientific Reports
Sliding Mode Controller (SMC) is a controller design method used for control systems, aimed at achieving robust and stable control of systems. To improve the performance of SMC, this paper applies a hybrid enhanced particle swarm optimization algorithm (HEPSO) to optimize the parameters, including [Formula: see text], [Formula: see text], ɛ and ...

Reversal of Chronic Stress‐Induced Inflammaging by Bazi Bushen Formula Through AMPK‐Sirtuins Axis Activation and Myeloid Reset

Exploration, EarlyView.
Chronic stressors trigger systemic immune remodeling marked by myeloid expansion and lymphoid suppression, and this immune imbalance subsequently drives tissue pathology through proinflammatory signaling and senescence amplification, with the lung and kidney confirmed as the most vulnerable target organs.

Dynamic Performance Enhancement of a High‐Agility Hypersonic Mechanical System via a Learning‐Augmented Robust Control Architecture

International Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT The design of control systems for high‐agility mechanical systems operating in extreme environments is a significant challenge in nonlinear dynamics. This paper addresses the complex dynamic control problem of a hypersonic interceptor, modeled as a multi‐input multi‐output (MIMO) mechanical system characterized by strong aerodynamic cross ...

Host‐induced silencing of the Minc09294 effector gene impairs Meloidogyne incognita and M. Enterolobii infection

Pest Management Science, EarlyView.
Host‐induced gene silencing of the effector candidate Minc09294 significantly impairs Meloidogyne incognita parasitism, markedly reducing gall formation, reproduction, and the development of specialized giant cells, with partial cross‐species effects on M.

H-Infinity Model Following Control for Uncertain Systems by Using Digital Redesign Sliding Mode Control

IEEE Access, 2020
In this article, we discuss the H∞ model following control for uncertain continuous systems by using a discrete sliding mode control (SMC). In contrast to the reports in the literature, the digital redesign technology is newly integrated with SMC ...

Comparative study between PI, FLC, SMC and Fuzzy sliding mode controllers of DFIG wind turbine

Journal of Renewable Energies, 2023
In speed control, double-fed-induction generator (DFIG) has attracted attention in wind energy conversion systems (WECs). These systems can offer higher performances by controlling converters that connect the generator windings to the grid network. Therefore, different control strategies have been used.

Sliding Mode Control in Aerospace Applications: A Survey

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT Sliding mode control (SMC) enjoys robustness to matched and unmatched (in the case of minimum phase input‐output dynamics) bounded perturbations, and finite time convergence. Second‐order and higher‐order sliding mode control systems (2‐SMC/HOSMC) retain all the advantages of sliding mode control, but in addition can be applied to systems of ...

Discrete Implementations Modify the Intuition of Final Set Adjustment in Barrier Function Based Control

International Journal of Robust and Nonlinear Control, EarlyView.
ABSTRACT This paper establishes an implementation‐aware framework for Barrier Function Adaptation (BFA) and shows that discrete‐time realizations fundamentally alter the logic of final‐set adjustment. In particular, sufficient conditions are derived to preserve the key benefits of BFA (predefined performance, gain adaptation with uncertain perturbation
