FCS Model-Free Predictive Control of a SP-CHB 5-Level Inverter as Shunt Active Power Filter Based on Extended State Observer Using Ultralocal Model
Single-phase cascaded H-bridge (SP-CHB) multi-level inverters controlled with the finite-control-set model predictive control (FCS-MPC) can be used as shunt active power filters to improve power quality; however, the FCS-MPC scheme is highly dependent on system parameters. That is, when there is a mismatch between the...
