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 ...

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.

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.

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 ...

Liquidus of MgO and MgAl2O4 in the CaO‐MgO‐Al2O3 System at 1550 and 1600°C

Journal of the American Ceramic Society, Volume 109, Issue 5, May 2026.
ABSTRACT In this study, the liquidus of MgO and MgAl2O4 spinel phase in the CaO‐MgO‐Al2O3 system at 1550 and 1600°C were experimentally investigated using a classical quenching method. In order to examine the liquidus composition accurately, the equilibration was carried out using four different ways using the combinations of Pt and ceramic (MgO and ...
