Optimal Control of Nonlinear Multivariable Systems [PDF]

Iranian Journal of Chemistry & Chemical Engineering, 2009
This paper concerns a study on the optimal control for nonlinear systems. An appropriate alternative in order to alleviate the nonlinearity of a system is the exact linearization approach.

A Design Methodology for the Seismic Retrofitting of Existing Frame Structures Post-Earthquake Incident Using Nonlinear Control Systems

Buildings, 2022
A structural design methodology for retrofitting weakened frame systems following earthquakes is developed and presented. The design procedure refers to frame systems in their degraded strength and stiffness states and restores their dynamic performance ...

Age‐Related Changes in Myeloid Cells and Their Impact on Subcutaneous Melanoma Growth in Mice

Aging and Cancer, EarlyView.
Our findings reveal that age‐related changes in subcutaneous melanoma growth and immunotherapy response are context‐dependent. In models where tumor growth and treatment resistance increase with age, this effect is partly driven by enhanced immunosuppression from myeloperoxidase‐active Gr‐1⁺ myeloid cells.

Tuning and Feasibility Analysis of Classical First-Order MIMO Non-Linear Sliding Mode Control Design for Industrial Applications

Machines, 2019
Model-based control techniques have been gaining more and more interest these days. These complex control systems are mostly based on theories, such as feedback linearization, model predictive control, adaptive and robust control.

On the stability of nonlinear controlled systems

Journal of Mathematical Analysis and Applications, 1962
AbstractIn this article, the problem of stability of non-linear controlled systems is discussed by the application of Liapunov's second method. Certain stability criteria based on the method proposed by A. I. Lur'e and some other simplified criteria of stability are given.

The rs10191329 Risk Allele Is Associated With Pronounced Retinal Layer Atrophy in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective To investigate whether the rs10191329 risk allele in the DYSF–ZNF638 locus, which is implicated in central nervous system resilience rather than immune‐mediated pathology, is associated with retinal layer thinning, a biomarker of neuroaxonal damage in relapsing multiple sclerosis (RMS). Methods From a prospective observational study,
