Cyberattack‐Resilient Fractional‐Order PPI Control for Frequency Regulation in PV‐Integrated Power Systems

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Load‐frequency control (LFC) comprises a primary process in interconnected electrical power systems, playing a critical role in maintaining the stability and reliability of the electrical grid. It is of paramount importance that the designed controller functions in an optimal manner, particularly with regard to the compression of area ...

A beam‐direction cross‐vessel metrology method and error analysis for the ptychography setup at HEPS ID09

Journal of Synchrotron Radiation, EarlyView.
A beamline‐direction cross‐vessel metrology method and error analysis for ptychography setup at HEPS ID09 is proposed and implemented. A 12.3 nm reconstruction resolution of ptychography demonstrates the validity of metrology.A metrology method dedicated to position monitoring and correction for the ptychography setup at the High Energy Photon Source ...

Towards an ‘absolute’ timing of biostratigraphic and environmental phases from the Saalian late glacial to the Weichselian pleniglacial in central Europe—Insights from a lacustrine succession in Lichtenberg, northern Germany

Boreas, EarlyView.
Palynological records are central to the biostratigraphic subdivision of the Late Pleistocene in central Europe. Yet many interglacial and interstadial phases—such as the Eemian, Brörup and Odderade—remain only poorly constrained in time due to limited numerical dating.

Design of a Three‐Phase PWM Rectifier Based on Improved Whale Optimization Algorithm Optimized Fuzzy Control

Advanced Control for Applications, Volume 8, Issue 3, September 2026.
Schematic diagram of the whale optimization algorithm (WOA)–optimized fuzzy proportional–integral–derivative (PID) controller. The WOA is employed to dynamically tune the scaling factor expressions and fuzzy control parameters (a(e)a(e), a(ec)a(ec), βpβp, βiβi), as well as the initial PID gains (kp0kp0, ki0ki0), based on the error (ee) and its ...

Tuning Fuzzy PID Controllers [PDF]

, 2012
After the development of fuzzy logic, an important application of it was developed in control systems and it is known as fuzzy PID controllers. They represent interest in order to be applied in practical applications instead of the linear PID controllers, in the feedback control of a variety of processes, due to their advantages imposed by the non ...

Dynamic, Unconstrained Optimization of Secreted Enzyme Production in Fed‐Batch Fermentation Using Reinforcement Learning

Biotechnology and Bioengineering, Volume 123, Issue 8, Page 2024-2036, August 2026.
ABSTRACT Reinforcement learning (RL) has been used to control a wide range of dynamic processes, especially ones that are too complex to model well or have stochastic environmental perturbations. Fed‐batch fermentations are subject to changes in starting cell growth rates and process variations that can affect cell growth and secreted target production.

Transient Response Analysis of Quasi‐Synchronization and Self‐Synchronization Grid‐Connection Processes for Nuclear Power (N + X) Emergency Diesel Generator Units

Engineering Reports, Volume 8, Issue 8, August 2026.
The upper portion condenses the five‐unit EDG arrangement into repeated diesel–governor and generator–AVR modules, distinguishing four operating units from one standby unit. Measured data and the equipment configuration jointly support a calibrated full‐system model, which then feeds two parallel research tracks covering self‐synchronization and quasi ...
