【Abstract】 The article applies Passivity-Based Control(PBC)theory to the design of single-phase LCL gridconnected inverter controller.A mathematical model of the system based on Euler-Lagrangian(EL)is established, and the resonant peak generated by the system is suppressed by the notch filter damping method, so that the system meets the requirements of grid connection.The simulation results verify the feasibility of the scheme.更多还原
