    Abstract

    The Passivity-Based Control (PBC) has been adopted in LCL-filtered Grid-Tied Inverters (GTI). However, the inaccurate mathematic model of control object will lead to a steady state error, when using the conventional PBC controller. In this paper, a modified PBC controller by using Dynamic Damping Injection (DDI) for LCL-filtered GTI is proposed to eliminate the steady state error. Furthermore, the state observer is used to reduce the number of sensors. A simulation platform is built in MATLAB/Simulink, and a 3-kW experimental device is developed with the control hardware of dSPACE DS1202 to verify the correctness and effectiveness of proposed control method.
