摘要：
The LCL filter is widely used in new energy grid-connected systems because of its good high-frequency filtering characteristics, but it is a third-order system, and the design of the controller is relatively complicated. By using the inherent fully actuated characteristics of the system, the mathematical model of the system can be transformed into a fully actuated model, which can greatly simplify the design of the controller. In this paper, the fully actuated mathematical model of the LCL grid-connected inverter is established, and its control strategy is derived. At last, the stability of the control strategy is verified by the simulations.
