Lyapunov Based Current Control Scheme for Grid-Connected Inverter

摘要

A novel current controlled scheme based on Lyapunov function has been proposed for the grid-connected inverter, only one control parameter need to be tuned in the proposed Lyapunov based controller, compared to the traditional proportional-integral controller. A simple control structure in proposed method is easy to be implemented and the designed controller can track the current reference quickly. Moreover, the injected current can still have a satisfied total rated-current distortion when connected to a distorted grid. The steady state and dynamic performance of the proposed control scheme has been validated by the comparative simulation results.
