Power Quality Enhancement in Grid‐Connected Photovoltaic Systems Using Hybrid Harbor Seal Whiskers Optimization and Interpretable Generalized Additive Neural Networks

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
The integration of solar energy into modern power grids supports sustainability and energy efficiency but also introduces power quality (PQ) challenges such as harmonic distortion, voltage sag, swell, and fluctuations. In order to reduce PQ problems in renewable energy systems (RESs), this research proposes a novel hybrid control strategy that combines

Current Control of Three‐Phase Inverter Using a Data‐Driven Model‐Free Adaptive Controller for Power Quality Improvement

International Transactions on Electrical Energy Systems, Volume 2026, Issue 1, 2026.
This paper introduces a data‐driven model‐free adaptive controller (DDMFAC) as a powerful, practical, and suitable alternative to improve the limitations, challenges, and inherent problems of conventional model–based methods. The proposed method, using input–output data processing independent of the mathematical and systematic model, acts as an ...

Analysis of a Satellite Antenna Azimuth‐Angle Positioning Control System Using a Genetic‐Algorithm–Based Proportional‐Integral–Derivative Controller

Journal of Control Science and Engineering, Volume 2026, Issue 1, 2026.
Precise satellite antenna control is essential for maintaining reliable communication links and signal accuracy. However, selecting an appropriate controller and tuning its parameters remain challenging because controller characteristics and parameter combinations strongly influence transient and steady‐state performance.

A Shadow‐Mode Digital Twin Shunt Active Power Filter Control Based on Meta‐Optimized Twin‐Delayed Deep Deterministic Policy Gradient Reinforcement Learning

Journal of Engineering, Volume 2026, Issue 1, 2026.
Most learning‐based shunt active power filter (SAPF) controllers still rely on fixed neural architectures, single‐metric rewards, and slow training cycles that limit deployment. This paper presents a digital twin–enabling (DT‐enabling) control framework for an SAPF that couples meta‐optimized twin‐delayed deep deterministic policy gradient ...

Real‐Time Implementation of Unknown Input Observer‐Based State and Unknown Disturbance Estimation for Series Active Filters

International Journal of Circuit Theory and Applications, Volume 53, Issue 7, Page 3970-3992, July 2025.
For the series active filter (SAF), a combined controller and observer scheme is proposed. Two controllers—state feedback (SFB) and linear quadratic regulator (LQR)—along with state observers, including the Luenberger observer (LO), proportional–integral observer (PIO), and unknown input observer (UIO), have been designed.
