Servo Control of Shunt-Active Power Filters Using Kalman Filter With DC-Link Reference [PDF]

E3S Web of Conferences
LQG servo controllers may regulate current flow in a SAPF (shunt-active power filter) provided by a balanced or unbalanced supply voltage. Balanced or uneven supply voltages power the SAPF.

Meta‐Optimized Twin Delayed DDPG Reinforcement Learning Agent for Multiobjective Control of Shunt Active Power Filters

Electronics Letters, Volume 62, Issue 1, January/December 2026.
A PSO‐aided TD3 agent is proposed to automate the neural topology design for active power filters, replacing manual tuning with algorithmic discovery. By converging on the minimal sufficient architecture, the framework slashes computational overhead by over 50%, enabling rapid offline retraining suitable for digital twin‐based adaptive grid control ...
