Adaptive Fuzzy Control of Three-Phase Grid-Connected Inverter

Research output: Contribution to conferencePaperpeer-review

Abstract

Three-phase grid-connected photovoltaic (PV) systems are most dominant in power system distribution applications. The LC filters are commonly employed in the PV grid-connected inverters. This paper presents a new adaptive fuzzy control for an inverter connected to the grid through an LC filter. The proposed controller exploits the concept of input-output feedback linearization and the approximation capability of fuzzy systems. The control objective is to control the inverter current components to prescribed reference values. The closed-loop system stability and the updating laws of the controller parameters are determined via Lyapunov analysis. Finally, the proposed controller is simulated, and results are presented to validate the effectiveness of the designed controller under different system disturbance and parameter uncertainties.
