摘要

针对三相并网逆变器，提出了一种模型参考滑模控制方法。首先，将电网的相电压和相电流作为目标函数;可以推导出相应的电网电压和电流状态方程。然后，设计了一种前馈控制方案来实现电流解耦。利用Lyapunov稳定性定理验证了解耦控制律下系统的稳定性。仿真结果验证了该方法的有效性。

Research on MRSMC for Three-phase Grid-Connected Inverter

A model reference sliding mode control(MRSMC) is proposed for the three-phase grid-connected inverter. Firstly, the phase voltage and current of the grid are set as the objective function. The corresponding state equations can be derived for the grid voltage and current. Then, a feedforward control scheme is designed to achieve current decouple. Moreover, the Lyapunov stability theorem is used to verify the stability of the system with the decoupled control law. The effectiveness of the proposed method is verified by the simulated results.
