Fractional Order PID Controller Design for Level Control of Three Tank System Based on Improved Cuckoo Optimization Algorithm [PDF]

Journal of Intelligent Procedures in Electrical Technology, 2015
Fractional-order PID (FOPID) controller is a generalization of standard PID controller using fractional calculus. Compared with the Standard PID controller, two adjustable variables “differential order” and “integral order” are added to the PID ...

Data driven drift correction for complex optical systems

Journal of Synchrotron Radiation, EarlyView.
Time varying Bayesian optimization as a data driven approach for robust drift correction is outlined, and its application for a split and delay x‐ray optical system is illustrated.To exploit the thousand‐fold increase in spectral brightness of modern light sources, increasingly intricate experiments are being conducted that demand extremely precise ...

Hover Flight Improvement of a Quadrotor Unmanned Aerial Vehicle Using PID Controllers with an Integral Effect Based on the Riemann–Liouville Fractional-Order Operator: A Deterministic Approach

Fractal and Fractional
The hovering flight of a quadrotor Unmanned Aerial Vehicle (UAV) refers to maintaining the aircraft in a fixed position in the air, without lateral, vertical, or rotational movements, using only the vehicle’s control systems to maintain proper balance in

Anemia‐associated mutations disrupt the CDIN1‐Codanin1 complex in inherited congenital dyserythropoietic anemia I (CDA‐I) disease

The FEBS Journal, EarlyView.
Congenital dyserythropoietic anemia type I (CDA‐I) arises from mutations in Codanin1 and CDIN1. Using quantitative biophysical approaches, we show that disease‐associated mutations disrupt the CDIN1‐Codanin1 complex. Our findings provide critical insights into the molecular mechanism that links protein dysfunction to disturbing chromatin arrangement ...

Application of Multiobjective Optimization Based on Modified SPEA2 Method for Tuning FOPID plus Second-Order Derivative Controller in Hydraulic Turbine Governing System

Journal of Electrical and Computer Engineering
The controller design and parameter tuning of the hydraulic turbine governing system are critical for ensuring stability and safety of operation. In this study, we propose a novel design of fractional-order PID plus second-order derivative (FOPID2D ...

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Vagus Nerve Stimulation Paired With Tones Alters the Auditory Cortex Proteome in a Rat Model of Rett Syndrome

Developmental Neurobiology, Volume 86, Issue 3, July 2026.
ABSTRACT Rett syndrome is a neurodevelopmental disorder caused by an X‐linked mutation of the MeCP2 gene. Individuals with Rett syndrome, as well as rodent models of this disorder, demonstrate abnormal cortical responses to sound, which impair auditory discrimination ability.

Cascaded Tilt Control‐Based Frequency Regulation of Renewable Energy Integrated Three Area Power System With Smart Transformer

Engineering Reports, Volume 8, Issue 5, May 2026.
Introducing a cascaded TI–TID secondary controller (SFO‐tuned) for a renewable‐integrated three‐area grid with HVDC and smart transformers modulating voltage‐dependent loads, achieving faster settling, lower overshoot, and robust frequency/tie‐line regulation under ±20% load changes versus conventional TI/TID baselines.
