Constrained FCS‐MPC‐Based Current Controller for Voltage Source Converters: Application to Shunt Active Power Filters

IET Electric Power Applications, Volume 19, Issue 1, January/December 2025.
In this paper, a constrained FCS‐MPC based current controller is introduced for controlling shunt active power filters. In the proposed current controller, the objective function is same as used in the conventional FCS‐MPC and a switching frequency constraint is considered to reduce the average switching frequency. The results obtained from FPGA in the
