Design and practical implementation of a fractional order proportional integral controller (FOPI) for a poorly damped fractional order process with time delay

, 2019
One of the most popular tuning procedures for the development of fractional order controllers is by imposing frequency domain constraints such as gain crossover frequency, phase margin and iso-damping properties.

Fractional Order PID Control of Rotor Suspension by Active Magnetic Bearings

, 2017
One of the key issues in control design for Active Magnetic Bearing (AMB) systems is the tradeoff between the simplicity of the controller structure and the performance of the closed-loop system.

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.

No More Differentiator in PID:Development of Nonlinear Lead for Precision Mechatronics

, 2018
Industrial PID consists of three elements: Lag (integrator), Lead (Differentiator) and Low Pass Filters (LPF). PID being a linear control method is inherently bounded by the waterbed effect due to which there exists a trade-off between precision ...

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.

Electrothermal Twisted and Coiled Polymer Artificial Muscles and Their Applications in Soft Robotics

Small Structures, Volume 7, Issue 5, May 2026.
Researchers develop a PE@SPN electrothermal polymer artificial muscle with a parallel‐stranded spiral structure. A temperature self‐sensing‐driven hierarchical closed‐loop fractional order PID (FOPID) control scheme is adopted. A rehabilitation manipulator was designed, and subsequently, a series of experiments are conducted to test the performance of ...

Feedback control of excitability and high K+ induced epileptiform bursts in male rat hippocampal slices with a photocaged adenosine A1 receptor agonist

British Journal of Pharmacology, Volume 183, Issue 10, Page 2578-2591, May 2026.
Background and Purpose Adenosine is a potent regulator of neurotransmission and neuronal excitability, through activation of Gi coupled adenosine A1 receptors (A1Rs). Adenosine has gained interest as an anticonvulsant because of its endogenous involvement in ending seizure activity, but peripheral side effects require local application.
