Mechanism and Control Analysis of Synchronous Frequency Resonance in Distributed Power Generation System Connected to Grid

Energy Science &Engineering, Volume 14, Issue 4, Page 2263-2276, April 2026.
Small‐signal modeling reveals that insufficient system damping positions conjugate poles near the imaginary axis, fundamentally explaining the SFR mechanism. A virtual resistance control is consequently proposed to damp the resonance and effectively suppress SFR, which is validated through Hardware‐in‐the‐Loop experiments.

Comparison of Fuzzy Logic and PID Control in H‐Bridge Inverter: Performance Analysis and Response Optimization

Engineering Reports, Volume 8, Issue 2, February 2026.
Under identical conditions, we benchmark PID against Fuzzy‐Logic control for a single‐phase H‐bridge inverter. FLC achieves faster rise/settling with lower THD and better disturbance rejection than tuned PID while requiring explicit rule design—offering a reproducible baseline and deployment guidance for power‐quality‐constrained inverter applications.
