Nowadays, the passivity-based control (PBC) as a nonlinear control method with much superiority has been studied more and more frequently, where it has been successfully used in Grid-Tied Inverters (GTI). Due to the high order characteristics of a LCL-filtered GTI, the PBC control law tends to be complicated, resulting in a difficult selection on control parameters. In this paper, a novel PBC parameters design strategy based on the expectant limited steady-state error is proposed. Simulation platform was built in MATLAB/Simulink and a 3-kW experimental device was carried out with DS1202 to verify the correctness and effectiveness of the proposed strategy
