Model Predictive Control for Three-Phase Four-Leg Grid-Tied Inverters

IEEE Access, 2017
In order to improve the quality of the power injected into a grid, this paper presents a model predictive control strategy for three-phase four-leg grid-tied inverters. For the convenience of optimization, the discrete-time model of the inverter in which

Reduced-Sensors-Based Predictive Controller for LC Filtered Four-Leg Inverters

IEEE Open Journal of Industry Applications, 2021
The high number ofsensors, ten in total, required by the traditional finite control set model predictive control (FCS-MPC) strategy of a four-leg inverter with LC output filter increases the complexity and cost of the system and limits the practical ...

Sliding mode control of four‐leg inverters in a stand‐alone microgrid for unbalance, neutral to ground voltage, and harmonics compensation

IET Renewable Power Generation, 2023
In a stand‐alone microgrid, voltage control is an important issue to keep the grid balanced under unbalanced load conditions. The other important challenges in microgrids include handling the neutral to the ground voltage (NGV) as well as total harmonic ...

Assessment of Model Predictive Voltage Control for Autonomous Four-Leg Inverter [PDF]

IEEE Access, 2020
The Finite control set model predictive control (FCS-MPC) is recently introduced to control inverters without the modulation stage. The absence of the modulation stage gives an unpredictable performance of the control system.
