为解决基于虚拟同步发电机VSG（virtual synchronous generator）控制的逆变器并网时电压、电流双闭环传统控制动态响应速度慢、鲁棒性差的问题，提出一种基于微分平坦理论的VSG新型双闭环控制策略。首先，根据三相并网逆变器拓扑结构建立dq坐标轴下的数学模型，并根据微分平坦理论证明了系统的平坦性；其次，设计了包括前馈参考轨迹和误差反馈补偿的电压和电流微分平坦控制器；最后，在MATLAB/Simulink中搭建了系统仿真模型。仿真结果表明，在功率扰动和电网三相短路的工况下，所提控制策略提高了基于VSG的并网逆变器的动态响应速度和鲁棒性，验证了VSG应用微分平坦控制策略的有效性和可行性。

To solve the problems of slow dynamic response speed and poor robustness in the conventional voltage and current dual-closed-loop control for grid-connected inverters based on virtual synchronous generator (VSG) control, a novel dual-closed-loop control strategy for VSG based on the differential flatness theory was proposed. First, a mathematical model under the dq coordinate axis was established according to the topology of a three-phase grid-connected inverter, and the flatness of the system was proved based on the differential flatness theory. Second, a voltage and current differential flatness controller including feedforward reference locus and error feedback compensation was designed. Finally, a simulation model of the system was constructed in MATLAB/Simulink. Simulation results show that the proposed control strategy improves the dynamic response speed and robustness of the VSG-based grid-connected inverter under the operating conditions of power disturbance and three-phase short-circuit fault of the grid, thereby verifying the effectiveness and feasibility of the differential flatness control strategy when it is applied to VSG.
