Voltage Sensorless Model Predictive Control for a Grid-Connected Inverter With LCL Filter

This article introduces a sensorless model predictive control (MPC) scheme for a grid-connected inverter with an inductive-capacitive-inductive ( LCL ) filter using only the grid-side current measurement. A state estimator and a disturbance observer are designed based on the Lyapunov stability theor...
