Tuning of dynamic feedback control for nonlinear mechanical systems [PDF]
2013 European Control Conference (ECC), 2013 Mechanical systems are often only equipped with position measurement encoders and obtain the velocity signal by differentiation. However, differentiation largely amplifies noise. In this paper we look at dynamic feedback control of Euler-Lagrange mechanical systems.

Linear repetitive control for a nonlinear mechanical ventilation system using feedback linearization
2021 IEEE Conference on Control Technology and Applications (CCTA), 2021 Mechanical ventilators sustain life of patients that are unable to breathe on their own. The aim of this paper is to improve pressure tracking performance of a nonlinear mechanical ventilation system using linear repetitive control, while guaranteeing stability.

Nonlinear output feedback H∞-control of mechanical systems under unilateral constraints
IFAC-PapersOnLine, 2015 Abstract The work focuses on the output feedback synthesis of hybrid mechanical systems under unilateral constraints. The problem of robust control of mechanical systems is addressed under unilateral constraints by designing a nonlinear state feedback H8-controller developed in the hybrid setting, covering impact phenomena.

Nonlinear cochlear mechanics without direct vibration-amplification feedback [PDF]
Physical Review Research, 2020 Recent in vivo recordings from the mammalian cochlea indicate that although the motion of the basilar membrane appears actively amplified and nonlinear only at frequencies relatively close to the peak of the response, the internal motions of the organ of Corti display these same features over a much wider range of frequencies.

An Improved Whale Optimization Algorithm Based on Nonlinear Parameters and Feedback Mechanism
International Journal of Computational Intelligence Systems, 2022 AbstractWhale optimization algorithm, as a relatively novel swarm-based intelligence optimization algorithm, has been extensively utilized in numerous scientific and engineering fields. The intent of this work was to devise a modified WOA based on multi-strategy, named MSWOA, to address somewhat deficiencies of the original WOA, such as converging ...
