Unified linear time-invariant model predictive control for strong nonlinear chaotic systems [PDF]

, 2016
It is well known that an alone linear controller is difficult to control a chaotic system, because intensive nonlinearities exist in such system. Meanwhile, depending closely on a precise mathematical modeling of the system and high computational ...

“Only the Blue‐Eyed Ones”: How Refugees' Origin and Gender Affect Selective Solidarity Through Perceived Similarity and Threat

Journal of Social Issues, Volume 81, Issue 3, September 2025.
ABSTRACT This paper investigates social psychological mechanisms underlying selective solidarity with refugees in two experimental studies conducted in Germany. We hypothesized, in line with the geopolitics of racialization and masculinization of refugees, and rooted in social–psychological theories, that refugee origin and gender affect expressions of

High Performance Decoupling Current Control by Linear Extended State Observer for Three-Phase Grid-Connected Inverter With an LCL Filter

IEEE Access, 2020
Compared with traditional single L-type filters, LCL filters for three-phase grid-connected inverters can suppress the switching voltage and current ripple better, thus reducing harmonic pollution to the power grid.

Design and Stability Analysis of Sliding Mode Controller for Non-Holonomic Differential Drive Mobile Robots

Machines, 2023
This paper presents a novel extended state observer (ESO) approach for a class of plants with nonlinear dynamics. The proposed observer estimates both the state variables and the total disturbance, which includes both exogenous and endogenous disturbance.
